I have a buddy that has an 04 dodge cummins, the truck stalls out everytime he hits bumpy roads and sometimes when its warming up. would it be an electrical problem or a lift pump replacement...thanks:evil

Sounds like is a loose connection. Vibration from the bumpy roads, and vibration during start up could be problem as well. Could be many different things, those could be just coincidences.
