car starts normally when turn the radio on the car suddenly stops.

What is your question?

The car runs normal and suddenly stops on the freeway. AC was on and the radio was on at the time of stop. All the light on the dashboard was on. I can not start the car any more. After about 40 minutes later I can start the car again but after drive about 1 minute it totally stopped again. It won't start. I found out once I turn on the car radio the car shuts off and will not start any more. Any suggestions? Thank you!
