Unfortunately I have to be a contributor to this thread.
Last August when we were north bound on I-39 somewhere between Bloomington, Ill. and Rockford, Ill. I went over a bump in the road caused by road construction.
All of a sudden my coach had no power. No electrical, no transmission, no engine, no nothing. I managed to coast to the side of the road and their we sat. When I turned my ignitions switch, to attempt to start the coach, nothing happened. I waited a few minutes and tried again and it started only to stop running again. I then went and looked into the battery compartment to see if maybe a battery had came loose and was shorting out against something but they were okay.
I then went back and attempted to start the coach and it started right up. It kept running so we headed out and made it back to Stevens Point, Wisconsin without further incident.
I took the coach up to my dealer who looked the coach over from front to back but they couldn't find a thing wrong with it. So, somewhere in my coach I have a problem waiting to jump out and bite me and there's nothing I can do to prevent it. Scary ain't it.:(
Had a problem something like yours only coach would not start after fueling. Towed, started at repair shop, they could not locate problem. another time one year later same problem but started after setting. two years later it became more frequent. Cummins west finally got it to duplicate problem. Was a wiring connection where wire was short of normal causing a connection that would pull away and not make contact. They lenghend wire and no problem since. I would bet on a connection that had no contact temporarily and caused your problem.
