Dear Customer,
thank you for your inquiry at JustAnswer! My name is ***** ***** I try to help you to find a solution for the problem, which is annoying, I understand.
A simple, often overlooked, trigger for an engine stall occurs when the heated gases inside the fuel tank can't vent properly. The pressure causes the gas flow to reverse and move out of the carburetor, effectively shutting the engine down. Often referred to as vapor lock, the engine can't operate with these heated gases trapped inside the tank. On lawn mowers, most vapor lock occurs through a dirty fuel tank cap. These caps have a small vent hole that allows the tank to maintain the proper pressure. Clean or replace the fuel cap.

This is just a suggestion off course, but it may help you to solve the problem, let me know it it worked, thank you.

Of course, I am always happy to help you anytime!

Kindly be patient whilst awaiting any responses from me as I'm not constantly available.

Best regards.

Hi gery thanks for that response if I leave the engine for 10 minutes it will start no problem and run again for 20 mins if I am going over thicker grass increasing the load that’s when the engine will stall does that effect your 1st suggestion?
Expert:  Gery66 replied 4 days ago.

Hi, yes I would say that has an effect, as the engine get's hot faster as a result!

Customer: replied 4 days ago.
I’ll try that and let you know the results ����
