Default Intermittent voltage drop while driving

Figure its either a bad battery or some electrical draw and don’t really know where to start, unfamiliar with electrical issues.
6 speed manual 89’

when the car is in motion i can Keep the engine running. The second i throw clutch in i can actively watch the voltage plummet to sub 13volts and watch my idle almost zero out before car goes dead. In Motion. Wheel locks up, very annoying (And dangerous)
during Colder months i can start the car and wait for the check engine light to come on and the car always ALWAYS smooths out, can drive a few miles before the problem makes itself known again

Im not quite sure where to start, but driving the car and actually hoping the check engine light comes on doesn't feel right Haha. When it does the car feels Brand New

has anyone dealt with similar issues?

code 44 and 45 Only. O2 sensor is new. I cleaned the ground and cleared the codes, but only those Two come back after driving the car a few times, on separate days.
