I have an 2001 artic cat 300 4x4 it has been stalling out and not restarting if you let it set it will restart. I have cleaned the air filter and replaced the spark plug. I have even replaced the fuel on off valve thinking it was clogged after I have done all this and it ran good for an hour in the mountians but it acted up again. I take this ATV way back in the mountains and I am afraid it wiil let me set one night. I never had a problem before do you have any suggestions

 

Is it electronic ignition? if so it is probably the ECM. You will have to have it checked at the dealer.

 

Welcome to the forums.....

It could be electrical problem as crzrlou stated above but i would pull the carb and give it a good cleaning first because i owned a 1993 Suzuki LT4WD 300 KQ that was doing the same thing you cat is doing ( The 1993 Suzuki LT4WD 300 KQ is the same machine as your 2001 Arctic cat 300 4x4 ) , the problem on my 93' Suzuki LT4WD 300 KQ 4x4 was dirt/trash in the tank to the carb ; my late cousin was the original owner of the 300 KQ and it did this same thing with him 2 times ( he took it to the Dealership both times and it was dirt/trash both times ) Suzuki covered it under warrany the first time and charged him $100 the second time !

I bought the KQ after my cousin passed away in the summer of 1999 from his sister , and it started doing the same thing when i was riding with my brother riding the KQ and me on my 1986 Honda TRX350FM Foreman 4x4 ; the first 2 times the KQ stalled on my brother we let it sit a few minutes and it would start and run a few miles then stall again .

The third time it stalled we couldn't get it to restart even after waiting an hour it was still wouldn't restart , so i towed him the last 5 miles to the parking lot loaded up and went home ; the next day i started checking it out to find it had dirt in the carb bowl while i was cleaning the fuel system out i pulled the fuel tank and the petcock for a good cleaning !

I flushed out the fuel tank , replaced the fuel hose , installed a clear fuel filter between the tank petcock and carb , dismantled the carb and gave it a good cleaning ; while i had the quad apart i checked and adjusted the valves put it back together and didn't have a problem ( sold it to my brother in Nov. 2005 ) a week after i bought my 2006 Arctic Cat 400 FIS 4x4 Auto !

It only takes a single grain of dirt/sand or debris to cause the carb float/needle to stick onen or closed , so i would try cleaning the fuel system first before taking it to a DealerShip a very costly $$$ bill ; whatever you deside to do i would get a good O.E.M. Factory Service and Repair Shop Manual it will pay for itself with just the first full servicing of you quad !
