There would be packet loss during periods of high upstream power if they were in response to noise. Upstream power rises because there's no response to station maintenance, either because it was drowned out due to noise or some other impediment or more rarely because of a problem on the downstream.
While power is ramping up TBB monitor will show loss as the data (ping response to TBB) fails to get through to the CMTS along with the station maintenance.

Okay thanks - there's a problem on the downstream here going by this, and likely close to your home. The guys on the VM forum should be able to sort you a tech visit.
