The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

I drove my blazer home from work, an hour later I tried to start it and it started and died. It would not start again. My mechanic says it is the fuel pump. I towed it to the garage and he's repairing it now.
I had to replace the fuel pump twice. First time the vehicle wouldn't start. Worked like a charm after the replacement, until the fuel gauge sensor failed. Second pump I have put in worked fine until the vehicle started stalling randomly. Kicking the gas tank to start it helped for a while. Checked the ground connection for the pump and it was rusty. Sanded it down with some sand paper, 50000 miles later still working fine.
