When you replaced the alternator, did you also replace the voltage regulator? I have read that on this truck, the voltage regulator is internal to the ECU and is located on the firewall near the ignition coil. You may be able to install a separate, dedicated voltage regulator available at your local auto parts store. Please note that you may have to rewire from the ECU connector to the stand-alone voltage regulator. Good luck.

I don't think running new wires will help. Somebody really needs to troubleshoot the system.You would need to know if the main wire is solid or not between the battery and the alternator, the one you have replaced. Then one small wire goes to the ASD relay and the other goes to the computer. The computer acts as the voltage regulator.

Defective fuel pump or fuel pump relay. Replace the fuel pump relay first.

ford is the only one with a reset button, possibly check the fuse and relay for the fuel pump

You need to figure out which one you are losing. You are either losing fuel, or spark. When the engine quits, immediately open the hood, and check for spark. Let us know what you find. Good luck!
