My problem is that the car starts when its cold really easy and runs great when I shut it off and re-start it it starts again but if I let it cool for a while about 30-45minutes it won't start, you can hear the fuel pump working and the starter working but the car won't start........when its cold again it fires like new again.......what can be causing this its driving me crazy......

 

Have you checked it for spark when it's not starting?
