There's some troubleshooting advice on the Pipewire wiki[1] you might want to try.
I'd also take a baseline when the sound is working by capturing the output of pw-dump, and then diff'ing the same command when the sound drops out. Also check bluetoothctl info 00:1B:66:E9:99:8F and see if the audio sink has a UUID present after the drop. If it doesn't that would suggest a firmware issue, if it's there but Pipewire doesn't see A2DP, more likely a Pipewire/BlueZ issue. 1h ago Getting the btmon traffic log as described in the wiki when the issue happens will be handy to add to the bug.
