My 6.7 ram suddenly shut off while running great. Would not restart. When trying to start nothing happens, starter does not start, nothing. Have lights and dashboard indicators.but all else is dead. Dealer states that no codes were set but he can't seem to figure out the problem. We are both getting frustrated. HELP

 

My '03 had an issue similar to that, but my truck didn't shut off while running, it just didn't start. Here was my fix. I hope your's is just as easy to fix.
Back to morning brew . . .
