My H3 died at a stoplight this morning. Why would it die? It restarted. Could it be alternator or belt problem? Help me please-so far it has been perfect and now I am freaking out. Thanx !

A couple of possibilities exist, a crank sensor faulty, or I have seen a faulty PCM cause a stall. If it was a belt or alternator, and made it to the point of stall, it would not have restarted. If your mileage, and year are correct, you should still be under warranty.
