Fox News DVR Issue

For years, I have gad several program record on different channels.   For a long time,  any Fox News scheduled recordings will stop recording at random scheduled  days.   I have to reboot the box to resume the scheduled recording for Fox News.  It will resume for a short time and then stop again for the Fox News only programs.  All other scheduled programs on different channels dont have this issue.

Why does it happen to these Fox News four prgrams only.?

Tech support solution is to reboot.  I can do that. It fixes the problem temporarily.
