Hi, i have a 700 efi arctic cat with a stalling problem when i enter mud/ water hole ,I have 130 miles on it no problem on trials its only when i go into a mud hole,i thought it might be an air cleaner problem but i added a snorkel kit still have the same problem.it stalls restarts but wont rev up just idles soon as you hit the gas it stalls it last about 20 minutes once your out of the mud/ water.then runs fine. contacted the dealer with no help.

 

Have you tried dy electric grease on your spark plug? Just pull the plug boot off the plug and fill it up with the grease then plug it back up.
