SYNC Timing Synchronization failure - Loss of Sync

Hi hopefully someone can help !

I'm getting Sync timing failures and looking at he logs downstream pre and post errors to a point when the router losses connectivity and goes into a reboot loop a power off reboot doesn't always correct the fault. I have found a work around though . If I disconnect the coax from the router when its in its reboot loop and reconnect it after 3-5 mins it re-establishes and behaves itself for 5-6 hours then off it goes again. I had an engineer out and he changed the router but its still happening. 

heres my log files
