Is the plug and harness at the back of the alternator in good shape? Might want to look at it closely, a good connection here is important. Unfortunately, the rebuilt units from the chain stores don't have a good track record on a 6.0 powered trucks. While they might work ok on a gasoline powered sedan, the load on them is pretty high with the diesel.
After going thru a couple of alternators myself, I took one to a local shop for repairs. After returning it the first time they fixed it by installing some different "heavy duty" parts and it's been working correctly for a couple of years now. Like yours the indication was an intermittent BAT light on the dash.

The problem with my Autozone alternator was the fact that the regulator needed to be replaced with one that had a higher set point. (14.2 instead of just 13.5)
