Hi my name is ***** ***** welcome to Just Answer. Will it start right back up ? How long eill it run before dying ?
Customer: replied 1 year ago.
It will not restart until the unit has cooled down. Sometimes takes up to an hour. When completely cold, it runs for about 15 minutes, then begins surging befor dying.

Ok it could be a couple of things , the engine could be losing spark or compression. If you get a spark tester it would be best to check for spark right after it dies . The other thing is compression , a 4 cycle engine needs over 60 psi to run, most riding mower engines have 90 to 120 psi . So you would have to check the compression before starting the engine and right after it dies , if it's 85 to 90 before starting and 55 right after it dies.. you know it's a compression issue
