I would bed the entire action and just below the chamber in front of the recoil lug and see if that doesn't eliminate the problem.
This sounds like one way or another you have a stress issue where the action or barrel is heating up and pressing against something causing a vertical error.
Is it completely free floated in front of the lug all the way out to the end of the forearm? If not that's probably where you will find the problem.
An Aluminum bedding block HELPS, it does not however eliminate stress points unless it has been machined perfectly.
