Don't know why the problem might be occurring but once you get back to
the login page there should be a power off button at the bottom of the
screen, which may then allow you to power down.

Have a look in the logs (System > Administration > Log File viewer)
immediately after the problem occurs and see if you can see anything.

Experiment with google search keywords to see if you can find anything
and try searching in launchpad
