I might die!
History-95 Road King new pulg wires, Dayna 2000i( yr old) new spark plugs.Top end done last yr. Miles pushing 300,000
Problem- Backfires to total loss of all power (electrical) at freeway speeds.
doesn't happen during the morning only when it heats up during the day. Always within a 1/2 of the same spot on the freeway on my way home (I might be wrong but that tells me it heats to the breaking point by then).
I turn off ignition for a bit (under 30sec) and it fires back up and I get home.
Last time I had this issue it was the main circuit breaker under the seat( Thanks DR. Hess) I assumed it was at fault again and replaced, but no luck still have the same problem.
Thanks in advance for any help and yes "Ive searched forum"

The 2000i is in the cam chest right? What exhaust do you have? I have heard that heat from the front pipe can "cook" and ignition. I know I had that issue on a factory cam position sensor on a '98 Ultra that I changed the pipes on.

I had the 2000I Ultima fail, the same as the Dyna, how to tell is have the timing cover off, when the engine dies see if the top dead center light on the ignition flashes when you crank it in the no start condition. If it flashes the ignition is working and a coil is breaking down, going to 2nd the ignition is failing tho.

Is there only one circuit breaker on this bike? If there are additional circuit breakers, you might want to change them all. I had a similar problem on my '93 Fatboy. I changed all four circuit breakers and the relay. I also cleaned up the battery ground connection under the seat with my dremel. I haven't had any problems since. Over a period of time circuit breakers will weaken thermally and may not be able to carry the designed load

Pipes are Thunder Header
Timing cover Ive had machined air flow cut into it, to keep air cooling a little stronger. Rain is not a big issue in Phoenix so not to concerned about it getting wet.
Would love to check ignition but cant make it fail at home only at speed and under load.
Im real dumb when it comes to electrical so please be real specific
Have manual and cant find other breakers.

there are more breakers than the main. i would change all of them. 1 breaker is for the ignition system, 1 for the lights. and 2 more for other stuff that i can't recall right now.

Hit it with a heat gun and see if it fails. Or hit it with freeze spray (Radio Shack) when it fails and see if it wakes it back up. Replace if it does.

ok took a heat gun to ignition and it ran like a champ at 200 degrees of air blowing on it, could the VOES switch cause this problem! Something is happening cause, I stop and let it set a few seconds and then restarts and runs fine.
