Bose L1 Pro 8 Random Shut Down

After being without problems for more than four months, my Bose L1 Pr 8 has started randomly turning off. It comes back on again, but again shuts down after a while, sometimes just a few minutes. I have reset the Bluetooth button (press and hold) and will repost progress - hopefully it will fix the problem. It has stayed on for more than 30 minutes so far. I connect (via bluetooth) a Samsung Galaxy S22 Ultra running Android 16.

Has anyone else has this problem?
