As I was driving down the road, the engine just shut off. I have been unable to get it to restart and had to be towed home. Lights and gauges all seem to work fine, making me think it's a fuel problem, tank is 1/2 full. I'm thinking fuel pump. Where is it located, in the tank or out? Thank you

Before you blame a broken fuel pump, make sure it's not a relay, fuse, connection, bad wiring etc.
Do you get power at the pump?

Hi, Thanks for answering. I checked the fuses and found the pump fuse blown, I replaced it drove 30 feet and it blew again. Could this be a bad relay causing this? I still have to chase the wires from the pump back to see if there is a break. I was also wondering if the pump was on it's way out if it would cause the fuse to blow, I'll check the wiring first though.

You have issues in your fuel pump circuit.
If your fuse blew up right away, you have too much load on the circuit
Check your ground connections, and all the wiring, connector, harness etc.

I checked the wiring and everything seems okay, I did find and replace a broken ground strap, I also replaced the fuel pump relay. Truck started and ran for about ten minutes, I put it in drive drove 20 feet and it died, fuse blown, I am wondering if a bad pump would cause the extra load, or a clogged strainer, or is a blown fuse always a broken or damaged wire?

Could be a pump shorting internally.

But I would check the wires from pin to pin make sure each wire is very similar in resistance and voltage drop when performed. Could try rewiring the whole pump harness could be wire that is broken inside of the harness, try a larger diameter wiring.
