I have replaced engine side wiring harness on a few trucks with intermittent shut down. It cured the problem.

Intermittent or random shutdown. U’re wasting money on changing parts like accessory relay or fuel solenoid, clutch fan assembly. This is where the problem is at. Go to the drivers side firewall, above the foot brake valve there are two wire harness. That supply power to all these parts. Remove the coupler and check the pins for good connections and corrosion. Inspect the backs of the couplers. This will solve u’re issue. Teddd
