Intermittent connection loss with CM400

I have been having intermittent problems for the last 3 days, internet randomly drops from all wired and wireless devices after

around 5 minutes or so. Plugged directly into my computer or through the wireless router it makes no difference. I am using a

CM400 and Archer TP Link C7. A tech came out and it happened to be working when he was here, he said the levels looked fine. I

attached some logs from the Modem, any help is appreciated. The modem is about 4 months old and has had 0 other issues.

The attached logs are after the modem was online for approximately 10 minutes.  Thank you again.
