I watched a video from late last year last night (you know, that is enough for an opinion) and that pause on the breaks is weird. If I hadn't read your post, I would have thought that it had broken down as well. It did spark a memory that the helix was causing a lot of grey-outs due to its intensity. Maybe part of this supposed downtime will be to take the helix out or to find a way to make it less intense.
By the way, the track looks nasty in that video. It looks like a mixture of rust and vomit.
