Craftsman Lawn tractor. Runs for about 20 minutes and then stops running. After it cool for 20 minutes it starts again. I have changed oil, spark lug, fuel

What is the problem above and how can I fix it? What parts? Model No. 917.275390.


Someone said it sounded like the vapor lock but I do not know where it is.

Thanks for this TIP! Just fixed mine today I purchased it and the prior owner said after 15 20 and sometimes 30 min it would shut off then would restart and shut off again over and over... He thought it was the seat sensor.... I pulled the solenoid off broke the plunger off stuck it back on cut the entire yard with no issues. Now I just need to figure out why the transmission if in neutral doesn't always go into neutral if you wiggle things etc it will but otherwise it's like locked in a gear drives me nuts. But so happy I found this even though it was a long time ago that it was posted it still does it on the new tractors! This one was only 2 years OLD!

Following. I am experiencing the same issue with a Craftsman 17.5HP LT1400 riding mower engine. I have shorted out the seat switch because that was causing a problem. Now have the stalls after 10 to 15 min. Plan to check the gas cap vent is working, and check that there is constant fuel flow to the carb.. Will replace the carb next to rule out the carb solenoid.
