Over the past month I have been experiencing alot of internet disconnects along with ping spikes while the internet is working. I checked my router logs and was seeing several t3 errors. After a lose of connection. I looked at my downstream bonded channels. It looks like the lowest channel was -30.9 dBmV . Is this the issue? Any help would be greatly appreciated.

Please post everything.
Your link is broken. It only gives a 404 error.

The downstream power is way out of spec on many of the channels. So is the SNR. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, and latency problems.
In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
Thank You!! I do not have any splitters so I called for a tech visit. During the day I was notified that there was work done in my neighborhood. I still kept the appointment, since I was not at home to check. Once the tech came out, I explained the low downstream power levels. The tech was testing the cables and concluded there was an issue with the tap. He could see the power levels fluctuating. This would require someone to come out and fix. Today xfinitity came out and fixed the issue. He said they found damage on the line by the main road(this was why I was notificed of work being done before my appointment). Then today, as he followed it back, he found multiple issues with water damage and animal bites on cables. Both guys were super nice and glad they explained the issue.
Thank You EG for the help! I thought the power level seemed low but it was nice to have someone confirm and understand what I was looking at.
Glad it got straightened out !
