Could be a half dozen different things. Have you been playing with the needles? Do you regulary clean\change your air filter? Might have got some dirt in your engine? Pull your clutch apart and check it first.

While on grass your wheels are not always touching the ground so it will slow down. Also the motor may be over-reving and over heating as a result. When I first started with nitro I did that to my T-maxx all the time.

First, read this thread and learn about proper nitro engine tuning: "the engine tuning bible"

Next, check the clutch and clutch bearings. Clutches are a wear item and have to be rebuilt. Clutch bell bearings go bad often and need replaced regularly.

Continuous running of an engine that's not tuned properly leads to worn out engines. Yours may be worn out and needs replaced.

Also, running a buggy in grass is very hard on the engine, the grass is a lot of drag on the car, making the engine work very hard. Run on shorter grass or dirt/gravel.

I know the clutch is not the Problem because the clutch was replaced not long ago I think there may be some dirt in its engine because the air filter fell off and some dirt got in but we th got most of it by tipping it upside down and and washing it out with fuel bat maybe we didn't get all of it how can I remove the rest of it and I don't think its warn out because it only a year old and I don't do any racing or anything I just like to go driving for fun but this problem is annoying

One good gulp of dirt is enough to send an engine to the boneyard. Take the engine apart and clean. Maybe you were lucky.

Deffenetly Pull your engine down and clean it out with nitro fuel.
when your engine is apart take time to inspect all the internal parts including the bearings..
Having said that Im of the opinion that your compression is on its way out wich is quite an easy fix with a new piston and liner...
I am Only taking an educated Guess..
