Modem rebooting every 48 hours

I have a 2-year-old Arris T25 modem.  Every two days between 9:30 am and 10:30 am, it reboots without any action by me.  The event log always reads the same:

PacketCable Events

MTA TFTP: Successful
Provisioning Complete
MTA PROV: Successful!
Voice Line State Change, Line Number = 1, Prev State = OOS, New State IS
Voice Line State Change, Line Number = 2, Prev State = OOS, New State = IS

DOCSIS Events

Four minutes before the reboot

Lost MDD Timeout;CM-MAC=c0:94:35:XX:XX:XX;CMTS-MAC=**.**.**.**.**.**. *;CM-QOS=1.1;CM-VER=3.1;
No Ranging Response received - T3 time-out;CM- MAC=c0:94:35:XX:XX:XX;CMTS-MAC-**.**.**.**.**.**;QOS=1.1;CM-VER=3.1;
Lost MDD Timeout; CM-MAC=c0:94:35:XX:XX:XX;CMTS- MAC **.**. **.**.**. **;CM-QOS=1.1;CM-VER=3.1;

Just before the reboot
MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM- MAC=c0:94:XX:XX:XX;CMTS-MAC=**.**. **.**.**.**;CM-QOS=1.1;CM-VER=3.1;

I'm trying to decide whether to replace the modem with the Netgear CM2050V-100NAS, or call xfinity.

Thanks.
