You would be given one fast pass. Similar happened to my son on a different ride. He was given a fast pass for any ride
In that case you should inform the ride crew as soon as you can so they cab respond properly. Probably they'll have to fix the issue and let you ride again when it's done.
We didnt have this issue but I would assume they would re-startas soon as possible and either let you wait if quick fix or you can come back later.
