Fuel Pump??
 

One of the kids at work has a 2001 S-10 with a 4.3 He was telling me that while he's driving the truck will shut off intermittently. He still has power (light's, radio, etc.) Sometimes it fires right back up and other times it turns over several times before it starts. Could this be a fuel pump going out? It sounds like it to me but I thought I would get some opinions. The PO said the pump had been replaced recently..... Any ideas?
