Also, with about the same frequency but not necessarily related, sometimes the clock gets lost and thinks it is a completely different time of day. It usually lasts a few hours and if I notice it I can adjust it in a second from settings, but if I don't I miss alarms, etc. I can't trust my phone at this point
What can I do?
I installed CM 11 on my Mini about a month ago. In general I've loved it, but ever since then, at random times independently of whether I'm using it or not, it will simply reboot. It may happen twice a day or once every 2/3 days. I don't think it battery as I've seen in posts with a similar problem, because after it restarts it has the same battery level as before.
