Engine shuts off while driving (1 Viewer)

[maddss]

94 LC, Items replaced, Plugs, wires, cap, rotor. To be replaced fuel filter sock and fuel filter. Air/oil separator installed and cleared high idle. Currently now have CEL 71.

1. LC starts fine. When the engine is cold or hot, the engine just stumbles, feels like its a fuel problem. Push on the pedal and rpm's do not change, can only go 5-15 mph.

2. LC at running temp, for no reason it just shuts off. Wait 30 secs and starts no problem.

Both problems occur then are gone for several days/weeks.

Any thoughts? Fuel Pump, Regulator, Relay, fuel pump resistor?

Fusible links and wiring harness by EGR and glove box.

@mct75 What wiring harness are you referring to by the glove box ? Links and Harness by EGR where checked a few weeks ago and both good.

Coming from the ECU. They are subject to being damaged by vibration against a metal rail. Can cause the injectors to stay on flooding out the engine.

What/where is the harness. I have had the glove box off before, not sure what harness I'm looking for.
