Hey guys newb to the forum here and this 94 has got me fooled! For starters it's a 94 5.7 tbi motor. 4x4 4l60. 310k miles completely stock other than exhaust. It started about a month ago when the truck would die on me when I was in OD lugging up hills. I would be able to get out and tap on the fuel filter and pump, fire it up and go on about my day. Easy fix. Replaced the fuel pump and filter. Got the whole unit and not the rebuild kit. Well it didn't stop my issue. So I moved to spark. Replaced coil, plugs, wires, cap, rotor"accel brand", & ignition control module. Still having the same issue. Just dies whenever it feels like it. I'll let it sit for a minute and it'll fire back up and drive. Sometimes for 30 feet and sometimes all the way home. Thinking I should check all the grounds maybe something is getting an intermittent bad connection? Unplugged the egr vacuum line and pig tail at idle with not change in idle. Truck has gutted cats. Idk guys I'm stumped. I appreciate any tips or info yall might have.
Edit.. I'm no longer having the problem only under heavy load. It'll just randomly die now but never at idle.
