DCX-3200-m Frequent reboot/reloading

For the last couple of weeks my STB (Motorola DCX-3200-m) has been going into a reload/reboot mode multiple times per day. Sometimes it operates properly for most of the day and then, at other times it will reload ~ 5-6 times in a row. The unit works fine when it is not reloading and prior to now it has been working fine for over a year. The front display will also occasionally display a 1008 message at the start of the reload process. I have removed the power to the unit and plugged it back in to see if doing that would help but it doesn't seem to change anything. Is the change to all digital TV possibly related to my problem? I also have Cox internet and phone and those services are working fine. (the internet is solid as a rock).  No changes have been made to my entertainment/home network in the last year. Is there something going on with my STB?
