Car starts and runs until it warms up, then it shuts off until cooled back down again.

Hi Steven,

This could be a couple of things so we need to start with a little more information. Do you know if there are any codes? Does it run rough while it is running?

I suspect it is either a sensor issue, fuel pump, or maybe a vacuum leak.

Here are a couple guides that walk you through these. Let me know if you have any codes and what you find with these tests.
