Yesterday i was driving my 2014 yfz450r in 4th gear when it suddenly started to slow down until it stopped completely. I've tried to start it again and i succeeded but it didn't last, it stopped again. I don't know what the problem could be. Anyone had this problem before?
 
I assume that there are no issues with your fuel right? i mean, it's not empty? 😅 you can also check if there the fuel filter is clogged or if the injector is faulty. Update us if you find the culprit!
 
Is your carburetor one of the aftermarket ones? Maybe the tors are not plugged in. Same thing happened to me before, had to use jumper cables just so I could compelte the circuit coming from the CDI.

Haven't experienced this but it could be the carb. Double check it and then get back to us here so you can try what @bombaysapphire is saying over here. :)

My take is the fuel pump, but it's also worth checking if the clutch is slipping or if there's an issue with the transmission. Getting a thorough look from a mechanic or checking for error codes could help pinpoint it.
