94 will start but dies at temp please help!
ok so here'* my problem. my 94 bonnie will start and run until it get up to operating temp around 200. then it chokes itself out and dies and won't restart until fully cooled off. I rented the scanner and used the obd 2 harness but it won't read. my trans am had a similar problem in that it wasn't getting power to the obd port and as such wouldn't give up the codes. What i am asking for is which fuse do i need to check that sends power to the obd port and has anyone else had this problem with the getting up to temp and dieing? It has run fine for 190,000 + miles only to give me my first hiccup now! I'm only the 3rd owner and i got it at 183,000. Any help is greatly appreciated.

You could try unplugging your engine coolant temp sensor and start your car. it could be a bad (ECT) engine coolant temp sensor. If it stays running after that than replace the sensor.
Has your car ever overheated before this started to happen?
Your car is OBD1
You could have it scanned at a car parts store. They scan for free. If you have one close by your home.
Let us know what you find.
This will help you to locate it and change it if needed:

I don't want to step on your feet but...your car is not OBD2
it'* OBD1 for sure...1994 was OBD1 or OBD1.5 at the very most
The Autozone link I provided had the whole procedure in finding the ECT and replacing it..even has a way to test it as well.
How much are you paying to rent the scanner? How much would it be to rent a OBD1-1.5 scanner?
