When driving truck sometimes it dies and will not restart

(1999 Ford F-150)
Does run a little rough. Do I focus more on gas area in the engine or something else

when this happens and it won't restart,take the gas cap off.listen real close at filler pipe.can you hear the fuel pump come on for 2 seconds while a helper turns the key to ON,NOT START and then it cuts off? it should do this every time the key is turned from off to on,pausing 5 seconds in the off position between key cycles.
