I'll still be surprised if anything other than compensator valve and it's activation is the problem. If you can time it so it fails where you can get into a friendly place and remove the fill cap, you can see if it is the issue.
In the relaxed photo, you can see it tipped a few degrees and uncovering the vent port. In the applied photo it is straight up and down and port closed. If you can access it when stuck, you can put your finger in and GENTLY push the stem toward front of car and see if pressure releases. If so, then either the valve is faulty or something is preventing the piston from traveling far enough for the lip on the end to catch the lower stem and activate it. If it is tipped, then the only other possibility is something has happened to the residual pressure valve.
Have you tried pulling back on pedal when things stuck?
