Loosing "ADD ON PACKAGE" channels only??

I have a "TiVo Premiere-4 and TIVO Roamio BASIC (Both are Four Tuner with M-Cable Card + Switched Video Adapter)" and for some reason I keep loosing authorization of only one of the programing packages from my local "COX" system titled "THE VARIETY PACK" (call/digital channel numbers are 2208 thru 2290) which happens to include BBCA-HD?!? This condition just started happening in late August, the Premiere has been in service since March 2014 (eBay purchase) and the Roamio (Refurbish direct from TIVO) was just installed this past week.

It seems to mainly happen on Saturday night around 7:45PM CST <It has happened at other random times, but like clock work/weekly for the Saturday night time> (or just before 'Dr Who' starts) so that this means that the program(s) do not record..!!

I get one of the following conditions / errors: {Paraphrased if not listed as on screen}

(1) Contact provider channel not authorized.

<call CSR and they '''re-ping'' account>

(2) Unable to tune week signal, contact provider.

<call CSR and they test from their end and all signals test strong>

(3) Black screen with no on screen message

<go into cable card settings and it shows a signal of 96% on all four tuners?!?>

This error condition lasts on all of this packages channels from 20 minutes to 45 minutes, when the error condition clears up. All other channels / packages that I subscribe to work just fine! As the COX CSR's are telling me that it is testing and working good, and when a tech comes to my home to check signal strength all is working well.



Any suggestions on how to trouble shoot this issue? :confused:
