I may have missed it, but have you totally eliminated the possibility of a bad connection?
At least a few times cleaning the contacts and reseating the plug has taken care of the issue.
As an aside, my VR is pretty close to a (wrapped) exhaust pipe, but given the engine orientation, the flow of air hits the VR first and the pipe is downwind, so to speak.
With my pusher configuration, the air flows right to left in the above photo, and the exhaust has been wrapped.
