2022 kx450 random shutoff

So thankfully this hasn't happened on something major but I have a 2022 kx450 with about 18hrs on it, over the weekend it randomly will spit and sputter and shut off almost like it blew up, but then restarts with no issue. Brought it back to the camper checked it out and while riding down a straight roadway I tapped the kill switch and it acted in the same way bogged down till it shut off, then re fired! Raced all weekend no issue come home to practice did it again but re fired I purchased a kill switch hoping that's my problem but has anyone seen this in a KX450 where your riding then all of a sudden it boggs out till it quits but re fires like nothing is wrong?

Any advise is appreciated thank you
