What's your VSS snapshot frequency? Increasing it you can shorten the tests as the problem should appear earlier. I'm doing the snapshot every 15 minutes. Just snapshots, no need to do a full backup. In my case a snapshot made for any reason (branching, moving to different host etc.) was causing the issue with similar probability.
