mine locks up on me while playing a Christmas playlist and need a reboot to recover. First time since I replaced all the caps and reloaded the OS a couple of weeks ago.
While I have the unit apart, I did noticed one of the power connector has some oxidation on it. I used DeoxIT to clean that out. If power connections is intermittent, the unit can lock up and/or reboot.
If you don't mind taking the cover off, take a look at those areas.
