This sounds like perhaps a problem with the carburetor. Stop by an auto parts store and pick up a can of spray carb/choke cleaner. Remove the air filter and then try to start the engine. When the engines goes to die out, spray a shot of carb cleaner down the throat of the carburetor and see if the engine will pick back up (even for a few seconds) and then try to die out again. If it does then it's most likely going to be a carburetor situation. You also mentioned that you put fresh gas in the machine, this leads me to believe that perhaps there was a bit of old gas in the tank to start with. This old gas will pool and go bad in the carburetor and cause problems like this.

You can


to read up on the procedure to clean the carburetor. This will most likely take care of this problem if you can keep the engine running with the carburetor cleaner.

If the carburetor cleaner does nothing to keep the engine running then there may be something going on with the fuel shutoff solenoid. You should hear the fuel solenoid "click" when you turn the key away from the "off" position. If you do not hear the "click", turn the key back to off and wait a few minutes, then grab the fuel solenoid on the bottom of the carburetor with one hand and turn the key to "on" (not start) with your other hand. You should feel the solenoid click on when you do that if you're unable to hear it. If you cannot verify the fuel solenoid working then you'll need to get a meter and check for voltage at the plug under the carburetor.

Let me know what you find with this and we can proceed if necessary.

Thank you for using Manage My Life!

I want to share my experience with my tractor that would run for 10 minutes, die, then run for 5 minutes, then die, etc. All my internet research led me to the fuel cut off switch that sits at the bottom of the carb. Ordered it off eBay for $38 since Sears wanted $68 shipped. Went to drain the gas before doing this and removed the fuel line from the fuel filter. The gas wouldn't run. I opened the gas cap, then the gas would run. I closed the gas cap, the fuel would eventually stop. I took off the gas cap and there is a little tiny vent hole in the middle. It was filled with dirt. I took a needle and cleaned out the hole and it worked fine. So if anyone has this problem, check there first. Free and easy fix.
