Oh, I messed up pin 1 on U302 (VDD) - it's actually 13.13V, so ok there.

I see what you are saying on INCOM/OUTCOM on U302. I just double checked:
12 INCOM: .64 steady
9 OUTCOM: climbs from 1-3 volts up to 6-7 volts everytime I probe it (climbs for about 30 seconds)

Are you suspecting U302?

[NOTE: I somehow started using the wrong U numbers, but will stick with the current U301/U302 for consistency]
