Check the oil level in the engine. When an engine starts and shuts off in a few minutes the oil level sensor is usually sensing low oil and shutting off the engine. Service the oil to the full mark and try it again. If it still persists disconnect ONE wire fromt the oil level sensor and try it yet again. If after disconnecting ONE wire from the oil level sensor the mower no longer does it's early shutting off routine the oil level sensor has failed or is very dirty. You can try cleaning it with gasoline before replacing it. Sometimes this solves the problem. Other times you just have to replace the oil level sensor.
There is the possibility of a seat safety switch problem also.
