Thanks for the help. I will check the fuses and fuel pump the previous owner hacked both up. Also a new sensor could never hurt on this old car. Here is another idea.

I talked to a buddy and he had a completely different idea. His bet was it was the cat not working right. Makes since to me. I was think heat was causing the problem in the first place. Anything in the engine bay is going to be up to heat in 20min. But the cat might take longer to start to mess up. Thats why it took an hour in to the journey for the problem to happen. My buddy said that after driving the car for an hour see if the exhaust is glow red or not. But now I cant remember if glowing red is good or bad. Ideas? The previous owner put a midas exhaust on the car that has a lifetime warranty. I'm going to look into and see if that warranty in transferable. They need to fix some other things with the exhaust anyways. Any ideas on the cat theory?
