The lawnmower was running then all of a sudden started to die out and cut off. I've been having to jump it off the starter solenoid or I guess that what it's called. As far as I know I've checked all safety switches , wires and gas cap and several other things. The only thing I can think of is the spark plug but I've got to get the tool to take it off. Could there be anything else I've overlooked? Please help me if you can!
