Hourly T3 and T4 timeouts causing unstable internet - no splitters installed

I'm having hourly T3 and T4 timeouts which is causing my internet to stop working for sometimes 5 minutes, to up to an hour.  I recently had a technical come out due to my modem losing signal and I had a good week of internet afterwards (he found an old splitter and removed it, now my line is directly connected to main input line).  For the last week, I've been having T3/T4 timeouts which are now happening every hour.  

Here is my current power levels, which do not change before or after the timeouts.

The technician did say that the middle downstream channels have low power readings, but cannot do anything about that until COVID passes.  My problem with this is that I've only had service for two months, and I've had problems the entire two months.  

Here are the error logs from my Motorola MG7700 modem:

Interesting enough, I just had a T4 timeout while typing this issue.  Can anyone see anything that I can do to fix this issue?  I've factory reset my modem and router.  I cannot move the modem to another cable drop as I only have one into the house.  Calling or messaging customer service has been less than helpful since I've started my service.  Any help would be appreciated.  

Thanks
