I am having a problem with my 96 GT. The car will start and than after a while of driving all of the accessories and radio will go out and a few minutes later the car will die. The battery is dead. I then jump it off and it will run fine again. I have checked the battery with a volt meter and am getting 12.5 volts when the car is off and 14.7 volts when the car is running. I cannot figure this thing out. Please, if someone has any idea of what could be causing this let me know. 
Thanks.
Thanks.
