Could be that it's stopping because it's going to sees up. Ecsesive pkay on piston rings
Dump the fuel in the tank, get new gas and new oil and start over. Get a carbeurator cleaner additive for the gas as your carb. is dirty resulting in the sporatic operation.
A spray carb. cleaner that you squirt into the air intake by removing the air filter will also work for you. In fact, when you are getting the carb. cleaner get a new air cleaner and a new spark plug. get back and let me know how u make out.

You might try blowing with compressed air around the cylinder and head to get rid of the accumulated sawdust. Also, the high speed needle on the carburetor might be set too lean--with engine warm, adjust CCW until engine 4-strokes unloaded, but smooths out when lightly loaded (cutting wood). If too rich, it won't stop 4-stroking.

when engine cool,, spray wd 40 into the switch and work it a dozen or so times and clen it out
SOURCE: Wont start when hot
might be coil ? you can test it with and ohm meter should be within specs on both primary and secondary sides ? but try this first to see if its a vapor lock or fuel hose issue ? when it wont start get you a can of starting fluid and spray the air filter see if it restarts then ? this will tell you its fuel not spark ? then you can recheck hoses and primerbulb ? hope this helps
SOURCE: When idling my jeep overheats. The cooling fan is
At idling speed an engine does build up a lot of heat and the cooling fan will kick in. In slow moving traffic or traffic jams the temperature gauge can touch the red - particularly on hot days. The reason it cools down when you start moving is because of the air flow through the radiator.
Presumably there are no leaks from the cooling system otherwise you would have mentioned it. In normal circumstances the fan will not be running as you are driving at speed, as the air-flow through the radiator is sufficient to cool things. The fan only kicks in to get rid of excess heat - and this usually occurs at idling speed or after you have parked the car.
If the fan is running all the time as you drive, this points to either a fault in the fan switch, or the car is running too hot. presumably in normal driving the fan isn't running and the temperature gauge reads normal?
It is common - in stationary traffic many cars overheat (particularly big engined models) try to stall and 'cut out'. Restarting can be difficult until the engine cools down.
Is your car overheating in normal driving conditions or just at idle speed? Overheating in normal driving conditions can be caused by things like a failing water pump, blocked radiator, collapsed hose, faulty thermostat or, in the worst case scenario, cylinder head problems.
Overheating at idling speed is 'common'. Check your coolant level. If your car isn't using/losing coolant then there probably is no major problem. You can flush out the cooling system and refill with new coolant - and also check your radiator. Are the cooling fins crumbling with age? Or maybe they're partly clogged with insects and debris from the road? A blast with a hosepipe wil sort that out ..
The question is how much does your car overheat in normal driving? If it doesn't .. it appears as though you have nothing to worry about as such. Most cars have 2 speed fans... the 2nd faster stage kicks in at some point dependant on engine temperature. Perfectly normal.
