Zero relased a firmware (MBB v35 and BMS v42) supposedly to solve the issue with BMS stuck in battery hibernation mode when powering on the bike, did you update to this latest firmware?

The issue is that when BMS is in hibernation and don't wake up at key on, it does not communicate with MBB and you will get 0% battery on the dash due to no canbus communication.
Every day the bike do a BMS autoreset this is why the day after the issue disappear, if you want to do a manual reset of the BMS, you can remove for few seconds the B+ fuse from the left side of long brick battery (on FXS it's located under the rubber, a little lower than OBD connector).
