My car shut off while driving and would not start even after cooling down. Had no engine light and no codes. Replaced the crank sensor and did a relearn. Ran good for about a week. Now when the temperature is up it shuts off at idle in park or driving when you stop. No engine light. No engine codes. After it cools down starts right up. 12.5 volts at the battery when the car is off. 14.5 volts when running.

Do you
have the same problem?
