Question: why when its warm outside, after I drive for about 20 minutes my truck wont start.

When its warm outside after driving for a while, once I cut my truck off, it won't start for a while...it has to sit for 30-45 minutes. I smell gasoline but no leaks..new fuel pump..only smell gasoline under the car not hood..remind you this only happen when the weather is nice..when its cold no problems or fumes..help me please no leaks at all.

If there is no spark when it is warm, I'd suspect a crank position sensor or an ignition module problem
