i have an 01 doge cummins 4x4 automatic trans. motor has no mods everything is stock i had a friend who accidently filled the truck with gas. truck never was started while gas was in tank we drained the gas out cleaned the tank and filled it with diesel. the truck ran great before. now when its cold it will start up and run perfect till it gets to operating tempature then it will shut off and its almost impossible to get it started till it cools back down then it will start perfect then again once it gets to operating tempature it will shut off. anyone have any ideas on what this could be? any help would be greatley appreciated
