89 comanche, 4.0 renix, auto tranny.
I dropped the stock fuel tank and installed a summit fuel cell and an walbro external fuel pump.
90% of the time the truck runs fine, but on several occasions the engine will suddenly begin to sputter and lose power. When the sputtering begins the more I press on the gas petal the more the rig sputters. Once the sputtering starts it will not stop till I turn the truck off and restart it, then it will run fine again.
The renix has a fuel pressure regulator on the fuel rail so I don't believe it's getting too much fuel. Any ideas?
