My Protege started to have this problem about six months ago everything will shoot down. It will die. First try they put a new battery, then it lasted a week them two alternators which lasted around 3 months each. The last time they replaced the terminal heads. But today I had the same problem, and they put another new alternator, but it lasted couple of hours. What else besides the battery or the alternator can cause this problem. Car will start once is jump started but it will not have enough juice to last long and operate any accesories. Please help.

Most likely a problem with the alternator wiring harness or battery terminals corroded where they attach to the engine block (for negative) or positive to starter solenoid.
