I have a 1993 dodge dakota 4x4 with the v8 5.2 L engine in it. The problem is that the auto shut off fuse keeps triping when the truck is driving. Once tripped it will continue to blow fuses untill the truck cools off for a few hours then like nothing was ever wrong it will take a new fuse and start and run fine for a few miles again then do it again. However I can start it and let it idle for hours and the fuse will never blow. So far I have checked the relays, injectors and ignition coil and could find no problem
