Kinda goofy, but I think I may have found the initial issue. The seat front raise up/down button on the passenger seat was making a weird noise when I got the car started. So I moved it up/down manually and the noise went away. It looks like it was stuck trying to move in the up position. So I'm hoping all this was is the seat control being stuck and that draining the battery.

I've got a Multimeter coming in the mail soon, so I'll check the alternator.. but for now I'll blame the seat.

 

I use Optima RedTop too. Just keep it on a maintainer if the car sits. These cars use (when stopped) about 1Ah/day. Optima RedTop batteries must always be above 80% of their capacity.
