Car runs fine but, about 30min into a trip it backfires and dies. Usually start right back up, on hot days it might not start for 10min or so. Its not a quick stall, it starts with a backfire, and loss of power like its starving for fuel, give it gas and its more backfiring even flames out the exhaust then finally it dies. Its much worse in warm weather. I'm getting good fuel pressure at all times, even when it wont fire back up. It usually fires back up so I cant get a spark or inj pulse reading, only strange thing from the scanmaster is the BL's hit 150 when mash the gas during the problem, no codes. I've been chasing this problem for months with no luck, i've changed ECM, Coil pack, Mod, Maf, Cranksensor, Cam sensor looks ok but dont know for sure, still quits if you run with it unplugged. Sometimes the car will stall in the same area so its definately heat related. Please help, any ideas on how to diagnois this problem would be greatly appreciated.
