96 302 5 spd, 4x4

Truck idles fine, and drives fine, but slightly above idle, it runs really rough, rev any higher and it runs smooth, but will also occasionally shut off, sometimes at idle and sometimes while driving.

Truck has had the shut off issue for a while, running out of ideas.

What's been replaced: fuel pump, fuel filter, distributor cap & rotor, plugs, plug wires, ignition module, ignition coil.

 

No codes, and this morning it started once, ran for about 2-3 seconds, and shut off, and wouldn't start again
