Shuts off after engine has warmed up and will not restart until the engine has cooled off?

Hello. Given the age and mileage, I'm betting on a failing fuel pump. It loses pressure as it warms up and eventually can't put out enough to start the car. You can borrow a fuel pressure gauge from the local parts store with a loan-a-tool program.

Here's how to run the test:

With the key on and engine off, you should get from 40.5-47.0 PSI. The car will not start on less fuel pressure than that. Of course be sure to get it where the car won't start before you check the pressure.

Here's our general guide on changing the fuel pump:

And I'm including AllDatas information on how to remove and reinstall the fuel tank (so you can change the pump) in the attached images.

Let us know how it goes.
