Default ? electrical

Twice I have been rolling out them miles and suddenly without warning as I'm coming to a stop my '05 Ultra Classic FLHTCUI just dies. After I pull and check all fuses which none of them are blown and I use a test light I can then start the bike and be on my way. I have no clue what could be causing this?? So I'm curious that after pulling and checking all the fuses, could there be some way something is being reset??, which allows the bike to start. Also, I only check the fuses on the left side of the bike none on the right. I have tried to chase each wire I can get to to check for a ground short or anything, I can't find anything. The only thing I haven't tried is DTC's.
Really need some help.

Have you checked the connections on the battery terminal and the ground cables? Also a good idea to load test the battery.

Sounds to me like the IAC valve needs to be cleaned with some carb. cleaner.

Know issue is the neutral safety switch causing this intermittent problem on your clutch side switch pack. Wife’s Softail Deluxe had the same issue. I replaced the Micro switch and haven’t had this issue since.

Hope this helps

If it restarts in a few minutes, it would be a waste of time to load test the battery.

Does the bike stop running, or do all the lights and everything die too?

WTF is it with people and load testing batteries?

Did they have that interlock in 05? Even so it doesn't effect a running bike, it is a permission to start a bike.

No neutral safety setup on that year bike.

Load test of a battery that obviously has sufficient cranking power is unnecessary (load test if the issue is slow cranking).

When bike quits, does entire electrical system go dead, part of electrical system?

Codes?

Are you still here???
