he's right , it could be the " mega fuse " which is buried behind the ignition coil pack on the V6. I just changed mine about two months ago. I had the same symptoms as yours did but my engine ran alot longer since i had recently replaced the battery. i believe that the fuse cost me about fifteen bucks, and i think it was a 175 amp fuse. I made the mistake of just changing the alt again since it was the third one i changed ( in seven years ) since i have owned the car now. You know that ASS-out of-U-ME syndrome?? Check your battery anyway, it too could be at the end of its' life. The alternator can be removed without taking the y-pipe off (even though it makes it easier) just the tie rod end needs to be popped off and pushed out of the way. Check out Ray's info.
