CM1150V Error Log De-Coding - Losing Internet Connection

Came down this morning to it completely off-line again 

All the images of the logs/status screen are in this pdf file

Attached is the Modem Status and the Error log from this morning before I did anything 

Then I Power Cycled the Modem and it immediately came back on line and reported Speed Test at Full Speed (the Modem Status and Speed Test for that condition are also reported in the file above) 

Then I went to revisit this page and refresh to report, no more than 2 minutes later - page would not load (nor any other); Speed test failed! 

I went through same 'trick' I found where I could repeatedly request Speed Test and it evntually kicked in *after about 10 sequential fails);

the other thing I found was while it was actually processing traffic it would (typically) stay alive - so I just launched a YouTube video in another tab to play in the background (which would also give me an instant indication of if/when the internet connection dropped) while composing this update; well after about 3 mins the video stalled and no other page would load; 

this time my repeated speed test request trick failed and after about 20 attempts forced to power cycle the modem again to complete this post. 

I should add that in that period where there is no internet (and Speed Test repeatedly fails with a 'No Internet' error) all the front panel status leds on the modem are normal - soild green, no apparent flickering
