FZ-150 Problem

I purchased a new FZ-150 about a month ago to take on a trip to Yellow Stone as I did not want to take my EOS and all its Lenses. I am very happy with the camera, but I sometimes receive a message that I must power cycle it. It happened this weekend at least 3 times when I was shooting video, but it has happened in the past when taking photos. Has anyone else had this problem? Am using Sandisk Class 10 cards in it.

Thanks,

Dale
