Will not start/run after it warms up

Yes sir. I've done everything in this thread now. Just got back from my drive and it stalled once but started right back up. Then parked it let it sit for 1 minute then tried starting it again and it started (before the temp sensor it would not start back up). Note: I also put a 180° thermostat in and it calls for 195° but since the problem only occurs at higher temperatures I figured it would help out.

I know you know what your talking about. I completely agree with you. That being said this car has had everything you can think of tested and checked. (Fuel pressure, spark, voltage of almost everything possible). The only sensor that was not changed was the temp sensor. No one ever thought of it because it never overheated. If this fixes the issue I will definitely throw a 195 thermastat in it. But for now the cooler the better.
