Stalling

What is your question?

My car runs fine for a while then stalls, I then need to let time past before it will start. I tried to show it to a freind, It started then stalled. I'ed disconnected the power from the fuel pump (releaseing fuel pressurer) for about 10 seconds and reconnected it. The car strated wright up. What would be the top possible reasons for this. Fuel filter; fuel pump; etc,. Thank you. Rev. Miller
