Yardman push mower is about 2-3 years old well taken care of. Rear bag mower. $135.00 model. Starts with one pull everytime. When mowing it mows about 6-10 rows starts missing and then quits. Starts right up and then stops about 1 row later. Wait awhile and then mows about 6-10 more rows. Any ideas on how to keep it running.

It may need a tuneup or ignition module replaced. Check the air filter, spark plug.
Good Day.

No bad gas, new or old in can or tank can always cause big problems. ALWAYS put STABIL in gas can & tanks of all gasoline equipment year around. Before 1st winter cold snap, if you have, put gas stabilizer in all gas containers/tanks! Keep spark plug cleaned. After removing spark plug on a no start it should be wet from getting gas if not check fuel lines. Helps to remove plug try to start several times, blows junk out of cylinder! Clean plug, check gap reinstall. Preventative maintenance cheapest routine on any engine. Lawn equip: Start of season change oil, filter, blow out cylinder, clean plug, clean grass area under deck, sharpen blade. I only run 93 octane in my lawn equip, no problems 8 years, with preventative maintenace! MikeC
