Riding Mower with B&S Engine 12 HP. The mower runs fine except when it is used for about two hours or more. When it gets hot it stalls under load. I have replaced the breather gasket which was no longer functional and it seemed to go for longer times without stalling. Have made adjustments per manual as far as tuning. The mower always starts when I attempt to restart though. I have cleaned the carburetor, replace the spark plug and air filter. Used clean new gas and changed the oil. Any suggestions would be appreciated!
I am wondering if I could have a vapor lock problem. If this could be the problem how could I solve it? Incidentally the mower is 12 years old and has been a good one. Only other thing would be a compression problem????

its the ignition coil, when they get hot they stall like that. I just replace mine last week was doing the same thing.

Hi you could have a galled piston. When i was younger my dad had a cub cadet. It would run fine till it got hot then it would shut off. We put some oil treatment in it and it would run just fine (less friction) Give it a try add some oil treatment it might help .

You might want to check that the cowling is free of debris. If it get clogged it will cause the engine to overheat.
