Have the ISP check the signal and line quality UP to the modem. 
Be sure there are not coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem.

Oh god no. Why am I just now learning about this???
I went ahead and installed/ran some tests after reading through badmodems.com. 
I installed PingPlotter and, well, I'll post some snips of my results and you tell me.

However, from what I've read regarding the issue..
(Which sounds like the Puma 6 chipset uProcessor essentially halting every x clock cycles)
It certainly appears that I'm experiencing that issue.

The modem I had before this CM700 was a an Arris SB6141. I found this out by a quick google search for T3 T4 timeouts and found my post from 2018: https://forums.timewarnercable.com/t5/Connectivity/T3-T4-Timeouts/td-p/151726
What I've been reading suggests that the SB6141 may have similar issues as it has the Puma5, but I'm also seeing people argue against this.

I am currently researching modems so I can replace this CM700, any recommendations?
If the SB6141 does truly have similar issues, that would make a lot of sense, since I've been dealing with this for the last 3 years and the problem has persisted through both SB6141 and CM700 modems.

Anyway, if you are familiar with the Puma6 chipset issue, definitely let me know if my PingPlotter results point to that problem. 
I ran it a few times at differing intervals. 1mS/1000Hz resolution surely makes some kind of problem stand out.

See attachment for 1mS/1Min ping results. I'll try to include the other tests, but it looks like 1 attachment/post.
Thanks for your help!
