When you turn the key to restart it, does it turn over, or does it do nothing?

I had a similar problem, it would die, and upon restart it would crank fine, just not fire up. After a few minutes, it would start again. My problem turned out to be the fuel pump.

hmm...well the fuel pump turns on and everything i thought it might be the ignition switch or ignition coil maybe
