Why does my mustang shut off when i turn on the head lights?
Here's a wild guess. Open your hood with the car running & the lights off. Have someone else turn on your lights on & listen to your alternator. Maybe the alternator is loading your engine & causing it to shut off.
As I said, it's a wild guess. Just trying to be helpful. Sometimes by looking at one thing you discover what the real problem is.
