Question about Cars & Trucks
Could be an ignition problem or one of the relays.
When it fails to start, you'll need to figure out if you are missing fuel pressure or spark to the plugs.

the fuel pump could actually be malfunctioning. and the reason that you are able to restart and drive again is because when you turn the key on it is allowing the fuel pump to pressureize your system. but while the fuel pump is continuasly running it is loosing the fuel pressure. this is common on the cheap fuel pumps. i am not sure about were you got the fuel pump from but in all of my experiances with this problem i find that the fuel pumps have been boughten at a napa store.
i hope this helps you out.
and you could attach a fuel pressure gauge on to the fuel rail and start the car and watch the pressure to see if it is droping.

I had a similar situation and after some research, I discovered it was doing what many referred to as "Phantom Stalling" It would only happen once in a while and when I wanted the mechanic to see it, it never happened for him.
Keep an eye every so often on your RPM gauge (beside the speedometer) and see if it cuts out completely and does not move when you speed up (shows 0 even though your still in in drive and moving). Mine would do that and after a few minutes the car would stall and I would have a hard time starting it back up.
What I found out was that my "Crankshaft sensor" had gone bad. I picked up a new one at AutoZone and had the mechanic replace it.
My car has not stalled since Ive had the sensor replaced and I found that when I was ideling, the idle was a lot smoother than befor.
Hope this helps you.
