CAX80 continuous reboot cycle during power outage while on generator power

Hi,

My CAX80 modem/router is going into a continuous reboot cycle while my house is on generator power during a local power outage. Power went out yesterday, I started my generator and was able to use the internet for about 30 minutes while on generator power and then it started doing the continuous reboot. 

Reading the forums here I learned that the CAX80 does this if it loses signal from the ISP. I was able to confirm from Xfinity as well as neighbors, who were also on generator power, that the internet was still working. Generator was producing full power, 120V, 60.2 Hz, and the house was only pulling 5 amps total. 

I've copied the modem event log and pasted below. There was another power outage this mornng from 4:30 am to 5:00 am but the house was not on generator power during that second outage. 

Does anyone have any ideas on why this would be or how to fix it?

Firmware V2.1.2.6

Cable firmware V1.02.08
