2018 yamaha grizzly stalls after a short ride

[marek porowski]

I was wondering if anybody seen that problem and know what could cause it 

it’s new to me 2018 Yamaha grizzly 700 with just over 4000km 

it starts fine and runs great until it gets to normal running temp. Fan turns on few times and than it stalls. If I try to start it right after It won’t start but if I let it cool for a while it will start and run normal for a bit and than stall again. 
so far I checked the stator output voltage and it’s around 22 volts AC between all 3 poles. I measured voltage on the battery while it runs and it’s around 14v so charging seems ok. 
I’ve read somewhere that it could be the coil but I’m not sure how to test it 

does anybody have any ideas what could that be ?

A repair manual would show you how to test the coil —primary and secondary, along with the spark plug wire...not sure what the readings are suppose to be, but would just need a multimeter and manual...  also could be a wired is getting to hot—shorting out after ran for bit

Thanks for the reply 

I ended up leaving it at the dealer for top end recall and I asked them to check that could be causing it to just shut down. They tested it and said it’s my stator. So I bought a stator and replaced it and it runs great since than. I guess it was giving out 22-24 volts ac when I tested it but I couldn’t really test resistance with my meter. 
I bought small digital voltage gauge and now I can always see if I’m loosing charging.
