Does it quit like switch is turned off? How long before it will restart?
Does it have spark when it quits? Remove spark plug and with spark plug grounded, see it has spark when cranking.
Spark plug wire has to be attached to spark plug, and plug has to be grounded to se spark, I keep an alligator clipped wire, to attach to plug and metal of the engine, so i can see spark. If spark is ok, then it has to be fuel related, maybe th efue line/strainer in the tank.
