As far as the battery, I'm not sure if a cell has crapped out on me or not. I (ignorantly) didn't think too much about the battery since it is only about a year and a half old, but we all know where assuming can lead us. I haven't been able to do any testing on it yet, but I will check the battery when I do get to it.
My gut is telling me the "voltage regulator" (if that's even what it's actually called), is failing on me, but ruling out these other potential suspects before I order up an external regulator. To my surprise, it really isn't too expensive though, which is a good thing. Far better than the price for a PCM I'm sure.
