Stalling After at Start Up...

[Golgade]

I dont know if this what Heat Soak is, but....recently the car has been stalling when you first start it after it warmed up. It starts then stalls within 2seconds, then it will be fine if you start it again. If it sits for a like a hour or so it starts fine. Its not really a problem right now, I just am worried about it getting worse. Any Ideas?
