Tons of problems! Rv complete shutdown while driving?!

If it happens again before you get home, try and keep track of all the surrounding conditions when it stops....ie...was it hot out, did you just climb a grade, had it been idling, fuel stop, etc. All of these conditions will help to diagnose it the next time. They don't always throw codes. By giving a better picture of what occurred it will be easier to help you.

Also a better description, like a 1998 Ford E350 Econoline Class C with 88000 miles, recent tune up, etc.
