my new Prophet rev2 if it turns off unexpectedly after about 2 minutes. What can be? I can hear something loose inside around the power connector area.

Best bet is to contact support for official answers and advice, especially if you bought it new recently / still under 1yr warranty.  They're always helpful and quick with replies:

If it were me -- and you can hear something loose / rattling around, you can probably just open it up and take a look inside... there may be an obvious solution, like a loose cable that needs to be fully plugged in.   There's some info about opening up the keyboard here:   https://www.sequential.com/rev2-voice-expansion-install/
