I have a 2007 F350 KR Dually 6.0 I bought new ten years ago, 112,000 miles. Have an Edge Juice with Attitude hooked up. Last week the truck stopped starting while hot. When cold, it is absolutely fine, starts and runs smoothly, I have no power loss, slight hesitation in the fuel pedal / response but that's always been the case. I just replaced the fuel pump and it's doing the same thing; starts fine when cold, will not start at all when warm/hot. Any help would be greatly appreciated.
