check engine light and wont rev up

[the silver bullet]

I have a 2013 pro with a power commander with a pipe and can I just got done riding all day ran great went to unload it off the trailer and the sled wouldn't rev up and when I would give it throttle it would die so I would feather the throttle to get it into the shop and the check engine light would come on and off I was wondering if anyone has had this problem
thanks

Throttle block froze. The throttle safety switch not working with ice in it. Make sure where the throttle flipper pivots it moves toward the front of the sled a bit and just don't pivot in place.
