When the car is cold it starts great.
I drive around the block, come home and turn the car off.
It now won't start again until it cools down.

New thermostat & temp sensor

When it wont start check fuel pressure, spark and injection pulse, sometimes when crank angel sensors over heat they shut down, and they function when they cool, but do the checks first and let me know what you find.
