Resetting Contour DVR too much

We've switched back to Cox less than a week ago with Contour DVR 2 connected by HDMI cable (not the one provided by Cox because our box cannot sit close enough to the tv for this). In the last 5 days, we've had to reset the DVR 3 times on 3 different days. This is the main box as we have not yet set up the Mini box.

Wednesday: No channels available like we didn't have service set up (but guide was visible)

Saturday: No audio; video worked 

Sunday: Video and audio blinking/going out for a few seconds about every 30 seconds while watching live and DVR tv

Is this normal? I don't believe we should need to reset the DVR on what is becoming a daily basis.  Is there something that can be causing this that I need to look into?
