Mine was doing something similar, just not as extreme. Turns out my (-) cable had started corroding at a bend and when the exposed wire would get wet, it would start acting up. Wire was extra long so I cut it and replaced the connector. Trace your wires and see if that's the culprit.
Had a similar issue yesterday on my buddy's yukon. His would charge for a little bit then all the idiot lights would light up on the dash and the gauge would drop down to the 12v tick, and eventually all the way to 9v. How do the windings look on the alternator? We replaced the alternator and all is well. His windings were very dark and the case had very dark spots near the front vents.

It obviously sounds like the alternator is bad. Replace it and see if it fixes your problem.

If your going to replace it as a guess and check your prolly best off upgrading it to something more efficient/powerful so if it doesn't fix it at least your going to be improving charging performance.

You can always return parts to vatozone and play dumb.

well i am a broke a$$ so the upgrade for $220 wasn't going to happen. i ended up swaping with one off my 2002 v6 (turns out its the same one, i didn't know) it fixed the problem. so went to advance and got the cheap one $89 not to bad. thank you everybody who gave their $.02 it really helped out, i love ls1truck.com.
