Skreen....haven't heard of this issue for awhile...Skreen module threads are on here somewhere...about starting running then dying.. Does it idle rough when it does run...as a problem with the crankshaft position sensor will do? That is a cheap fix if it is the CPS. But it may be the other problem which isn't a quick or easy fix.... So, without rambling on, I would replace the CPS...first...
There is a safety switch on the clutch peddle. It must be functioning properly as well...depress clutch all the way down as well...
