if possible, have your alternator stress tested at a local auto shop. the regulator can go bad, still showing a 14v charge, but not completely charging your battery. your not showing any dummy lights? has it ever died while you are driving, or is it happening overnite? i see you live in michigan, cold weather can burn out batteries very quickly.
I had something like this happen to me not too long ago and it turned out to be the light switch on the steering column...the internals shorted out and it was drawing power from my battery as it sat...I say do the stress test and then have them check for any draws on the battery as its sitting
