Have to continualy restart clutch varies in amount of time between restarts as much as 15 minutes. What could be the problem.

Hi,
I moved your post since you attached it to one that began in 2005. It is most likely an intermittent switch that causes it to shut off. Suspect the seat switch as having become too sensitive if it is in the base of the seat. You may also wish to touch the housing on theclutch to see how hot it is since it could be overheating and going open.
Peace,
