Finally, after a ton of tech visits, the ultimate problem causing this issue has been found: A bad cable from the top of the telephone pole (at the tap) running 15' to the base of the telephone pole (ground block).

It looks like its happening every couple days and for only a short period.
From reading your website and documenting what all you've done, you've hit most bases.
The only things I might try?
1. I've seen moisture in coax cables cause issues. Usually its more frequently then every other day. If there was rain in the line (you put they replaced) but then had issues with it being loose at the amp, might there still be moisture in the new drop?
2. grounds. make sure the splitters are properly grounded. I've seen grounds connected back to neutral on a seperate coax connection that bled interference back into the system. Boy was that a pain to figure out since that leg wasn't even used. I found it by disconnecting everything and slowing adding things back in until I found the leg that caused the issues. then it was troubleshooting that leg to see where the issue was.
3. Maybe its the firmware on the cm1000 that the isp uses. It wouldn't be unheard of. Maybe its submitting a call to the cmts in error and causing issues. Sadly, not much we can do to test that one.
Thanks, all good suggestions.
