Is there somebody out there who knows about them? OK I'm at my Church mowing the yard. The only place I MOW, it takes me 4 hours to mow the whole place.. On my 60" Diesel mower with 300hrs, been mowing for about 30 min. THEN The engine STOPS, I take off the blades put my foot on the breaks and it stays running. I take my foot off the breaks and it cuts off no spuddering, just a STOP... I put on the breaks arms are back, turn the key and nothing happens... I set there for 10 min It Starts and keeps running and I go back mowing.. I been mowing about a hour and a half and it does it again, this time it shuts off, I mean no spuddering just shuts down. I put my breaks on and it now keeps going. I take my foot off the breaks and it dies. Press down hard and it keeps running.. It sets 10 min I take foot off break and its good to go... I mow another hour fine.. I call the dealer shop guy tells me sounds like your break switch.. I finish up take it there put a switch on. I come home after I eat supper I start on my 3 acre yard... I been mowing 45 min and it does it again.. I put on my break and it keeps running, this time I let off and it keeps running, I do another 30 min finish the yard.. Shop man told me it could be a seat switch. But the break will keep it running. Id sure like some help on this.

New to this forum. I've searched and read several threads about this but I need help for my specific problem. Item: Craftsman Mid-Engine Electric Start 30" Mower/Mulcher Hydrostatic Drive model 5363.270320 (Riding mower) Engine: Briggs & Stratton model 21B807-3026-E1 Problem: Flywheel turns but engine won't start. Started acting up in beginning of season with intermittent stalling. Now no longer stats at all. Having read previous posts I'm almost convinced the flywheel key is sheared (item 24 p/n 222698s). I've got gas in the carb and the fuel solenoid is operational. I'm quite sure I'm getting spark. My problem is getting the flywheel off. The plastic fan on top of the flywheel is held on with a bolt (not a nut). How do I prevent the fly wheel from rotating? I noticed an approximately 3/8" dia hole in the side of geared flywheel that is exposed as if a steel rod can be used to insert and hold as a counter pry against the socket wrench. But, I have no place to wedge the rod against. Is this is what that hole is for? Can I get a helper to hold the bar while I try to loosen the bolt? Or is that hole just a machined hole to balance the flywheel? Since I'm not absolutely convinced that the key is sheared I'm reluctant to buy special tools that I'll never used again.
