Issues with lambda getting "stuck" at 0.83

Issue with lambda getting stuck when doing a power pull, issue started out of no where and consistently getting worse so the point that I can no longer read lambda under large loads.

Wiring has been checked, and re-checked... Sensor is new.

Sensor had a hard time to calibrate at the beginning (seemed like heater wasn't activating correctly all the time under calibration) I had to start/stop the calibration process a few times in order to get the O2 heater activated for free air cal. Seemed to read fine otherwise and is accurate under light loads @ idle.

Lambda sensor eventually recovers in approx 2-3 seconds of overrun:
