Car starts and will run fine for approximately 30 minutes. It then sputters and stalls. If I let the car cool down, it will start and repeat the above.

Good afternoon,

When it does not run, you need to check for both spark and fuel pressure to see has been lost.

It could be a fuel pump or it could be a crank sensor dropping out.

Do you have any stored codes?

I would start by verifying fuel pressure (if you haven't already anyways). I have attached the procedure for your car if you have not done this yet.
