My mower runs fine for about three quarters of an acre then the clutch kicks out if you turn the clutch back off and try to turn it on it doesn't kick in but if you shut the key off restart the engine the clutch will go in but will only last for about a minute or two then kicks back out if you let it set for about five minutes it'll run for about 10 minutes any suggestions. I've changed the seat switch PTO switch and ignition hasn't helped
