7/10 Update:
I checked the static and running pressures. They are now the same for some reason. Both at 85/100. Ambient is around 90F. I guess that means the compressor is doing nothing, and it is possibly losing pressure, but how the frick did the low side get to 85psi, when it was only filled to 50?
My arm does not fit in the engine compartment, so I can't unplug the compressor to test electrical signal

Plugged condenser or dryer can cause higher than normal low side pressure. So can low refrigerant, plugged or dirty air filter, expansion valve, and a few other things.
If you have lower than normal high side pressure and higher than normal low side pressure, your compressor is probably bad. I bet it fails a leak test.
