Check alignment of the speed sensor magnet with the sensor itself - I has this issue and it turned out the magnet wasn't close enough to the sensor - it was line up correctly but needed a washed behind the sensor itself to close the distance - when under loas the flex in the wheel was enough to cause it to momentarily cut the power, not helped by the fact my wheel had gone out of true.

Maybe ride in trail mode instead of boost too long. I rode in trail mode, climbing over 1 hour, no issue. I use boost occasionally, 1 time using boost less than 10 min on long boring road climb, no issue.

I had these error codes sometime last year, ended up with motor being replaced. Codes started out only happening occasionaly and powering off sytem and back on I would be able to finish my ride. Until 1 ride I got these codes and it never went away. If reinstalling software / updates did not fix the problem, I also did this as it was recommended, you most likely will end up with a new motor.

Hopefully that’s what will happen took video of problem as it’s fine for a bit I’m getting a bit fed up with shimano it’s ruining bike park days that you take time off work for thinking if pulling trigger on kenevo instead
