I'm in St. Marys. Just about 40 min north of Jacksonville Fl off 95.

Is there maybe some type of interlock or safety with the oil pump? I know I might be reaching into left field or something. Perhaps there is a safety that causes the bike to shut off if it's not getting the right amount of oil through the engine. Just trying to think outside th box.

ok, try this.
Get a voltmeter
Attach it to the Plus side of the coil, attach ground.
turn on key (do not start the bike)
while watching the meter, stand the bike up
Watch for a drop in voltage or lack thereof. An old analog meter (faster response visually) would be best for this.
You can then try this trick at other voltage locations as well.
A pin can prick a wire and be sealed afterwards with some spray on electrical tape (for locations you can't otherwise reach)

A little on the far side for me (about 300 miles!) But I am looking to do a run soon.

Is the bike EFI or carb?
If EFI the tip over switch is located inside the EHC and I don't believe it's serviceable.
Whether EFI or carb, I suggest you,
1: key on while watching EHC. Should have yellow on and steady, green below flashing. Stand the bike up and do you thing. If lights go out maybe problem is in key circuit. If lights stay active go to two.
2: With key on and yellow and green on, press Run. Now a red EHC light comes on. Stand up bike and do your thing. If light goes out then maybe run circuit is being compromised. If all stays on then go to three.
3: Start bike while observing EHC lights. Yellow should remain constant on, green below it should be flashing, and red should be on and flashing with maybe no particular pattern.
4: there is also a flashing light on the ignition module you can watch as you stand it up.
It's a start but least work towards a solution through a process of elimination.
When I purchased my wifes 06 Mastiff, it also had all kinds of extraneous B.S. wired into it. All that stuff came off first.
Good luck

I was away all weekend, so I will try all the suggestions this week. I think I have the EHC RIP installed. It is carb as well.

So, you need to identify which ehc you have and then become familiar with its indicator lights. I believe the picture with red and blue lights on is your ignition module in operation. If your not working with a service manual I suggest you get one if you plan on tackling these situations. I believe you can download one from this forum.
If your hunny is like my hunny I highly suggest you get this ironed out before you let her back on as I believe your next failure is your third strike. You gotta get a hit to run the bases

Yes, I know on all respects. There are no markings on the EHC, so I am not sure how I will be able to figure that out. I know the service manuals are available through dropbox, however with the different mods, I am not sure if the service manual will address it. I am sure it will give me some places to look and troubleshoot though. I am glad the service manuals are there, even though they can be hard to navigate.So, you need to identify which ehc you have and then become familiar with its indicator lights.

Well I am not sure if it is good or bad news. After looking at several wiring diagrams and images, I think I have an AIH RHC. Based on the connection and the HC in the earlier pix, that is what I have determained. I will start looking into that as well. Not really looking forward to it though. So unfortuneatly the earlier suggestions on looking for the lights as indicators won't work.

How about asking the person you bought it from?

I think you are correct. I never seen one like that before. So I goggled AIH RHC and yes it looks like yours. Not sure how to help?

Ok, try this if possible.
Start the bike and then move the modules (simulate standing bike up) might tell you if there is a tilt sensor screwing with you that maybe is in the wrong position.

Went through the wires again and still can't find anything. With the seat off, I strattled the bike and looked at the lights on the ignition module. This is where the "clicking" sound is coming from. The red light would come on Andy I could watch it go off and on while rocking the bike back and forth. Click on and off. While on the side stand, I had the bike running and it runs fine. I jiggled the wires to the RHC & connections, the ignition module & those connections, the handle bar cables and nothing. The bike wouldn't die. However when stood up the lights on the ignition module go out and the bike dies. Could this be the culprit or something else? Still searching.

did you ever do the one test I suggested of watching the voltage at the coil?
I would chase the power wires to the igniton module. I know that can be a pain but something is cutting that power.

Not y
not yet. I need to pick up a pin the get through the insulation. Hoping to get to that this weekend.

Ok. Finally got to it. Checked the voltage on the battery and a steady 13 volts. Checked all the wires on the coil and ignition switch. All checked out good with 12.5 volts. Same results with the bike on stand or upright. No visibly damaged or frayed wires on the coil or ignition switch. At a loss!

May be a stretch, but could it be one of these 2 breakers being worn out?

what's that wire behind on left on the bottom "breaker"
Check and make sure that horns not moving too and hitting the terminal.
