Some Brigg's and Stratten motors have an oil level switch. When you go on a slope if it is really steep the oil level switch will think there is no oil in the motor so it will shut off. If you have that steep of lawn your best bet is to get a lawnboy lawnmower because they don't have that problem - they use mixed fuel.
it could be caused by a few different things. the pneumatic governor or a fuel issue. an easy test is to hold the throttle on the carb closed to an idle. if it continues to surge then it is a carb issue, if it stops it is a governor issue
When the grass stops growing--some time in early-mid December. Then start mowing when it starts to green up--some time in March.
The steep slope stops and slows down the wind,then the wind goes back to normal speed.

Continental Slope
After sitting all winter, it could have water in the gas. Add some dry gas and fill with fresh fuel. If it's an older engine, the coil might quit working when it gets hot. Next time it stops running check to see if you still have spark at the plug.
Friction will cause a body to slow down or stop moving. A weight on a down slope will descend faster if the slope in wet, as the water will act as a lubricant.
The R train travels from Park Slope to Union Square with a total of 8 stops in between. The journey typically includes stops such as 9th Street, 4th Avenue/9th Street, and others before reaching Union Square. Overall, it can take around 30 minutes, depending on the time of day and train frequency.
The force that stops an object from sliding down a grassy slope is friction. Friction is the resistance between the object and the surface it is sliding on, which helps to prevent movement. The rough texture of the grass, along with the force of gravity acting on the object, creates enough friction to keep it in place.
check to be sure the blades have free movement. usually if you have this problem it is caused from something stopping the blades from rotating therefore it stops the engine
Bad armature or coil. They are heat-sensitive.
Assuming this is a vertical shaft unit look at the base of the engine. You'll see a small plug with either a thumb handle or 2 pips to unscrew the plug. After you remove the plug add good quality oil to the top of the cast slot in the bore of the plug opening. To drain look under the unit for a square pipe plug. Drain oil warm and replace plug after all dripping stops, refill with fresh oil.
