Check the power and ground connections first. Alternator voltage output is
controlled via the PCM (no internal regulator) so have any auto-store
(Auto-Zone, PepBoys, etc.) check it for output (voltage with 12v applied and
amperage). You may also have either some water/derbis in the alternator or
some loose connections inside of it (brushes for example).
Check the battery AND the Battery Temp Sensor under the battery (loose
connections).

Subject: DML: Alternator, signs of dying?
Buddy here at work has a 2000 QC, 4.7L Auto A/C and asked me this...
"What are the signs of the alternator dying? While driving along the lights
will go dim, engine will run rough. This has happened a few times with each
time lasting longer then the time before. Started out for a few seconds and
now its up to about half a minute. The voltage meter dose drop way down.
When the power comes back the voltage meter takes a few minutes to read just
past the top center line."
He didn't say anything about the engine light and I forgot to ask about it
and pulling codes. The battery was replaced last November.
Any help here would be appreciated!! Thanks!!
