I have a couple questions on this. Did your car just die or did it slowly die. My car is doing the same thing. It will start just fine with a jump and then run for about 4 minutes and then start to die. All the lights will start to blink and then it will start to sputter out almost like its lacking gas. The only thing is that my battery light is not on.
