I wasn't able to verified for spark but it acted the same way. I read on car forum about the crank position sensor causing the same issue as what I seen on my UTV. Since the part is not that expensive and difficult to get to, I went ahead and replace them anyway. Once that replaced, everything work fine and the engine seem to be a little more responsive and less noisy as well. We took it out a few more times for couple trips over an hour ride at the time. No problem so far.

Quick update on the issue and resolution.

I went ahead and replace the crankcase sensor along with both of the ignition coils. We took the UTV out for about an hour over the weekend without any stall. So I think the problem is fixed. 

I think it simply let it wait 10-15 minutes. The colane is cool to touch to begin with so unless the engine oil is hot. Thank you for your help.

My 2018 Hisun sector crew engine cut off after about 15 minutes run. There is no indicator of what is wrong, no error code just die and won't restart until it cool down. I notice that the fan is not running but the temp indicator is on low temp, no overheat indicator. I checked the radiator fluid, it is cool to touch.

Cooling fans are working, I can hear it running once awhile if I can get the engine warm up enough.  Thank you for all the help.

I want to change the transmission oil for my Sector Crew 1000 but cannot find the information on what type of transmission fluid this UTV use. I even called Hisun but they don't know it either. I get different answer each time I call. The service manual doesn't have any information on the transmission.

Thank you
