My 2000 Protege ES died the other day when I was driving, just turned off completely, no power. I wasn't able too start it so I had to get it towed to my house. According to one of my neighbors, he said he had this happen to a car of his and it was the cars computer that needed to be replaced. Another neighbor said it was the alternator. I tried to start it a few days later and it wanted to turn, but it just couldn't so I had my brother try to jump my car but no dice. Months before this, my car shut off completely on the freeway when I was driving, but came back on its own. This had happened twice. So far, I guess it's either the alternator or the computer. Do you think it can be either of those problems or something else like the voltage regulator?
