E53 N62 4.8 - cut out - “oxygen sensors disconnected”?

Hi all - bit of a strange one - my X5 cut out a few minutes after driving. Loss of power and judder - felt like gearbox was failing - and then it stalled. I switched it off and it fired straight back up - was slightly juddery for a bit but otherwise all ok.

Just hooked it up to dis and also inpa - and it lists three fault codes:

2C3B - Oxygen sensor before catalytic converter, not connected
2C3C - Oxygen sensor before catalytic converter 2, not connected
2C6E - Oxygen sensor after catalytic converter 2, ageing - friction threshold not reached.

Car has 119,000 miles on and all four o2 sensors were replaced with bosch sensors 19,000 miles ago (4 years ago). The faults seemed to trigger at exactly the same time and mileage (corresponding with the car cutting out). Unlikely both sensors failed at the same time - unless it’s perhaps because the sensors don’t “ engage” until after a few minutes after they’ve warmed up?

Grateful for thoughts please?!
