RDK-03033 Errors

About a week ago, we started getting three or four cable box crashes a day. The video just locks up and the cable box needs to be restarted. The "My Account" app still thinks everything is fine and there are no outages. I've checked the connections and they are all tight. At this point not sure what to do next. To recap, we did the following:

1. Check connections
2. Restarted cable box
3. Uplugged cable box for 30 seconds and repowered

Although each time the box restarts, it is still crashing 3 to 4 times a day. Any ideas would be appreciated
