Car won't start when engine warm

[IDriveFords]

I have a 91' 240sx coupe that seems to have some sort of ignition problem. When the car is cold it starts good with some slight studdering that clears up almost immediatly and then the car drives great. The problem happens when I cut the car off to go into a store or something and then come back out and try to start it; the starter kicks over but the car won't start. If I let it cool off which usually takes upwards of an hour it'll crank right over. I'm pretty sure it has to do with the ignition system and something getting to hot and then not working. The problem is definetly tempurature related. Any suggestions? Also my speedo and heads up display stopped working, but I think that has something to do with the heads up display system.

look at the spark when you cant start it. is it orange?

look up starting in tutorial link in my signature. what is your fuel pressure if you have a gauge.
