"the only thing they have in common is their power source: the batter and alternator."

Thanks Twisted & Vehi, that was kind of what I was leaning towards but wasn't sure if all of the symptoms would relate to the same issue or if I maybe had two seperate issues. I didn't want to start tearing into my harness' without an obvious cause and effect.
If I pull the alternator ("I" meaning hubby, lol) and take it to be tested - if the problem is sporadic like it's been - will it show it's bad if the issue doesn't happen to be going on at the time of testing? Also, how big of a pain in the butt is removing and replacing it?

You guys are awesome! Thanks again. I'll keep you informed of my progress.
