ok here is what my car is doing. I was driving down the road and the radio started to cut out. I turned the car off and it would not restart. I jump started it and it ran for about a mile then cut off again. i let it sit for about 30 mins it started on its own and went for about half a mile and cut off again. i jumped started it again and then it did the same thing. the fuel was low almost empty. i added some fuel while in the yard and it was running but the battery light came on. what does it sound like is wrong with it?
