Take the alternator belt off and see if it stops. Could be the internal bearing.

The water pump can also make a funny noise when it does out.

Take it back to the shop and have them look at it. They may have done something dumb that can be undone easily. Only they know what they touched/changed.

Could be as simple as drive belts are TOO tight for whatever reason...the less you operate it in this condition the better.
