CM1000 Rebooting serveral times a day.

[snaber]

I loose internet connection serveral times a day.  Watching the modem I notice it is rebooting.  The firmware is Firmware Version

V3.01.04

Looking at the logs they seems to be the same each time.  Called my ISP and they are saying signal looks fine on their end and since I havce my own modem there isn't anything they can do.  Anyone have any ideas if it is the modem or something else?

Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 

Try a different modem as a quick test to see if the problem continues or not. Try one from the ISP as a loner.
