i'm also 99% sure that its your alternator. you can go to autozone and they'll check it for you. When your battery light comes on, that means there's a problem with your charging system (alternator). When the alternator dies, the car is running solely off the battery and if the battery gets low enough, everything goes crazy. If you hadn't shut your car off, it would've eventually quit on its own as the electric current needed to run fuel injectors, sensors, and the cpu would've dropped below the acceptable level.
