I have an MTD, self propelled lawm mower with a 5.5 HP Briggs and Stratton engine. Over the last several weeks, it has developed a problem where it starts right up, runs for about 20 minutes and stops. Sometimes it coughs and sputters for awhile before stalling, other times it's as if it was turned off. There have been times it's done that and would restart, other times, I have to wait until the next day. I have checked the air filter, checked the gas line, and checked the spark plug cable. What I haven't done is replaced the spark plug. If this helps, I thought it started moving alot faster about the time it happened but for the life of me, I can't see how that would be connected to the problem.
