Maybe the fuel pump?

Truck died on me a few months back. It had been having a hard time for a while and finally quit.

Randomly, if I'm at a light or whatever, it would idle way down and act like it wanted to die. It would only do it briefly and then straighten back up. I'm thinking if it were internal, it would do it more frequently, but it just seems to do it when it wants to. Thought it was bad gas so I ran some treatment through it.

When it finally died, I realized there wasn't any fuel in the filter and changed the pump. Fired right up and ran good...now it's doing the same thing again. The parts store had a Carter pump (thought they were supposed to be pretty good?) and that's what I put on it about a year ago and that's what I put on it a few months ago.

Is there anything that could make the pumps go bad or just my luck on a pump?
