Sounds like your Alternator quit, if so it will not start soon or will die on the road.

the alternator is but a few months old. the voltage meter remains high, the alternator is working just fine... it's been doing the dip thing for a while now and i just want to get rid of it. so, would this be a short somewhere i could get to and fix it?

For a while I had a beaten up end on my positive battery cable. It wouldn't tighten well anymore and I was just too lazy to fix it. Every once in a while the truck wouldn't start, and I knew right away what it was...the battery cable AGAIN. Anyway, back to the point of all this. One of the tell tale signs that I was going to have to retighten soon was the exact symptom you're describing. The truck didn't always do it, but when I did notice it I'd just hop out, give the cable a twist on the terminal and All Better.

Start simple, remove battery cables, clean the terminals and reinstall. Just my $.02
