Car won't start when engine is warm.
Car is an auto 04.5. Car has never done this before until saturday. Saturday i went down to fast intentions to get my true dual exhuast put on and when they we're finished we took it out for a spin and came back and parked it. Went inside, did the payment thing, came back out to leave and when i turned the key over it turned over but almost instantly the rpms dropped to zero and the car shut off. Started again but this time i gave it a little gas and it caught and i drove home. Parked it at home for about 5 hours and went to get back in and she started right up no problem. Drove for 30 mins, ran a quick errand, got back in and it did the same thing. I've proven that it only happens when warm but i'm still not sure what the cause would be. Is this a simple computer tuning problem or something worse? 
Summary: Car won't start when warm unless i give it a little gas when turning the key over. Starts right up with no problems when engine is cold. Any ideas?

sounds like your idle is low/rough...did they touch your intake (even a small leak can cause poor idle/engine to die)?
here's what I'm thinking:
-cold start: engine idles higher, so it doesn't die
-warm start: engine idles low enough that is dies
Does the engine die when it's warm and at idle (at a stop light?)
*what other mods do you have?

No the engine has yet to die at idle once i give it a little gas to get started. I even got stuck at a train and it sat there idling. And there is no other mods done to it.
I'm really thinking you're having the same problem I was having. I believe when you "reset" the ECU by disconnecting the battery, it doesn't relearn how to idle when its warm. I've reset my ECU twice by d/c the battery and its happened both times. I started using the other method and haven't had the issue happen again.
Try reseting the ECU with the link I gave you on your other thread and see if that works.
