I have a ~1993 Lawnboy Silver series push mower with a 2-stroke engine. Lately it has been stopping while mowing. It usualy will start back up. Sometimes it quites a couple times during mowing and others more. Always has started back up. It seems to me that the coil is going bad. these mowers have solid state ignition coils. Will these act like otherecoils when they get hot they can stop working?
