Howdy all,  CFMoto newbie here. 

Bought the 2017 800 trail a few months ago and drove it 150 or so miles with no issues.  Changed the oil and got a uni-filter first thing.
had about 1000 miles on it when purchases. 

Was using it this past week on an elk hunt.  Ran great for the first two days then started running rough inconsistently.  Would run fine for a bit then lose power, then would die, and would be hard to restart.  After several attempts to restart it would finally stumble and start but would then run inconsistently, sometime good and sometimes rough til finally it died and would no longer restart.  It does have a code P0174 (lean condition) which could be any number of things.  I was driving at 8,500 to 9,500 feet so if anything it should be running rich.  I did clean the uni-filter and re-oil the foam.  The fuel pump seems to be working as it should but I have no way to check pressure.  Any thoughts on where to start? I'm thinking it some kind of electrical gremlin due to the sudden and inconsistent symptoms. 

Secondly, where's the fuse panel on this model?  I did find a couple relays under the driver's seat and what appears to be the ECU in front of the dash but no other fuse panels that I can see under the dash (I did remove the panel under the switches and display) , under the front package compartment, or in the engine bay. 

Any help is much appreciated. 

Thanks

The main fuse is under the drover's seat which you already found. The distribution box is clipped on the right side of the steering column but there is a plastic panel that has to come off first. Sense this started with the installation of the uni, pull and clean the mass airflow/air temp sensor center of the intake manifold. ONLY use mass airflow sensor cleaner. IF you find it is covered with oil only, its excess from the air cleaner. There are only a few foam filter oil treatments that dry enough not to atomize and travel up the intake..and cover that sensor. This may not be all the problem but it will be a part of it. IF you find it is also covered with dust/dirt, you can thank the previous owner for not concerting to a Uni right away....and know that units that were used in dusty condition running the OE paper filter got less then 1200 miles on average before needing rebuilt. Back to foam filters, in all filter oils always use a paper towel on the inside to sop-up any loose extra and always let them dry completely before using.
This is a pic on my fuse box which should be the same up to 2017.

Late reply.  Thanks for the info and tips.  Was back out elk hunting and really didn't have much time to look at it.  I found all the fuses.  No issues there.  Cleaned the mass air flow sensor (with MAF cleaner).  It didn't look dirty or oily.  Pulled the plugs.  They looked fine.  Still will not start.  It's still on the trailer so I'll run it down to the CF Moto dealer in the area.  They're about 60 miles away.  Hope to get it back before the snow flies so I can hook up the plow.
