I tested everything, besides the cam crank sensor. Ok, what happens is, when it won't start(cranks over, and it won't fire), its got gas pressure, no vacuum leaks, cylinder compression i good(at least thats what my co-workers say). Now, the thing it doesn't have is spark. After it cools down, it fires right up. At my shop I've had a car that would die while driving and wouldn't start until it has cooled down. The answer was a crank sensor. I'm going to take my chances tomorrow, and see what happens after i change the sensors on the Thunderchicken(common sense to change them every once in a while). I'll keep you posted. Thanks for the hint, i'll check that first thing.
