It the pump cannot reach the minimum required pressure (I think it is around 56 psi), there is a check valve that will not let any fuel to the engine.
If you keep having problems with the pump, (starting at the battery) I would check the electrical system. Low voltage (or amperage) could be causing performance problems with the pump.
Try jump starting your truck the next time it happens. (the extra battery power may make a difference)
