This issue has been corrected with the release of 3.4.
Apr 16, 2016
We have identified an issue that can cause rapid aircraft deceleration under certain conditions starting with Autopilot 3.3. When observing the behavior, it may appear that the aircraft is twitching at regular intervals. We are currently working to correct this issue and will release a new version as soon as we have sufficiently tested the fix. In the meantime it is still safe to fly with Autopilot, as the worst case scenario is the aircraft will just briefly stop and hover.
