every once in while the light on dash blink and the car died

What is your question?

I bought the car about a month ago and I have notice the light in dash blink once and the clock on the radio reset itself and the car died. It restart right away. it happens twice so far once while the a/c was on and the other while coming to a complete stop. the previous owner was not helpful and said that is why he sold the car with no warranty whatsoever
