If you charge the battery and than let it run by itself, the battery will begin to slowly drain without recharging itself as you press the gas.

I'm going through what I believe is a busted alternator right now. Give me an hour and I'll tell you how it went.

Alternator is most likely going bad. Does your car start right back up after this happens? If your alternator is bad your car is trying to run on pure battery power and getting zero if little charge from your alternator. When this happens little by little your car will run out of power to everything and in turn shut off.


How do you know when alternator is bad?

Typically you know your alternator is out when you have to jump start your car numerous times. A way you can test it is by turning on your car and while it's running discount the + terminal. If the car turns off then your alternator is bad. If the car remains in then alternator is good and possible bad battery. Hope this helps
