How old is your ? Sounds like ignition problem,If your engine is older you would have points when the points are bad they can stick together and will result in shutdown after unit cools a little it will restart !

Stx38 won't start

Actually, this is a problem with many lawn tractors. John Deere makes a "Starter Assist Kit" that sells for about $25. After time, the electrical connections get a bit corroded and when you turn the key the solenoid doesn't get the full current it needs to be activated. I have made my own relay to overcome this problem on my STX38, have shared with many folks with positive results as well. Cost is about $5 total. If you still have this problem and would like a schematic of the "fix", go to:, go the the Lawn and Garden section, click on John Deere. When the page opens, search STX38 and look for the thread started by "Brad". Info is in there.

Good Luck.
