I have the fix!
I had all of the same symtoms, all were intermitant then at the end it finally got worse. Zero volts shortly after starting, draining the battery, then it finally died, luckily in my garage. PCM? Alternator? Battery? Cables? Alternator and battery tested good, though not in the failed condition at the time. I really didn't want to shotgun parts at it, nor did I want to take it in for repairs that would be costly. Out of curiosity I pulled the alternator and took the cover off to expose the brushes. They were pretty much shot and the area was very dirty. I ordered a new set of brushes from Maniac Electric Motor online, under $15 shipped. Ordered on Friday, had them on Monday (Texas to Colorado.) Took 20 minutes to re-install everything and bam! No more issues. Strong charge, good indications on volt meter. I have only driven 40 miles, but I saw no deflection on the gauge so I'm good. $15, I'm very happy! Any questions let me know, I'll be happy to help!
