Challenger 750 no power

[Sledge]

I have a 2016 cub cadet challenger 750. In the past month it has started to lose power at about 25 mph, sounds like it is struggling for fuel. Any suggestions?

Could be a restriction on the high speed jet in the carb, 

Does it do it while driving only or in Neutral just reving?

[Sledge]

Does it while driving.

Main jet issue.  Probably some tarnish or trash or fleck of gasket. This is a carburetor model, right?

[Sledge]

Yes

If the driver seatbelt is not clicked in it will cut power at around that speed as a safety feature to ensure you wear your seatbelt. I just click mine in behind my back.  Not sure if that feature is on the carbureted model. If it is there have been reports of the seatbelt module going bad.
