Riding mower runs about 10 - 30 minutes then cuts off as if running out of gas . let it sit for about 5 minutes then it will start back up and run for about 10 more minutes and cut off. fuel in fuel filter
Mine would run for about 15 minutes and die. I pulled the carb off and thoroughly cleaned it. Inside the float bowl there is a plastic device held on by two phillips headed screws. Under this device are two tiny tubes with small holes in the side of them. Make sure these are clean. I used carb cleaner in a spray can and a tip cleaner. Make sure to wear eye protection if you use spray cleaner. I reinstalled the carb and, so far, it is working fine.

make sure the small vent hole on top of the gas cap is not clogged. Mine did the same thing and then I found mine was packed with dirt.

These ride-ons have a cut out solinoid under the carby that when there is no power or the ign is cut it will drive a little pin into the main jet to prevent flooding, id say this is why your mower runs for 20 and stops...
There is a few reasons this could be occuring:
#1First I would be checking the battery see if its dropped a cell or has a dead cell, you can do this by load testing it with a load tester or removing it and taking it into a battery specialist. if this is the case the battery will not accept a charge from the charging circuit...
#2 Check your wiring with a multimeter from the armature under the flywheel all the way back to your battery (also these models may have a regulator/rectifier that can be tested they have test values and can be checked by your local small engine repaier)
#3 If all your wiring is ok then you will have a problem with your armature this is located under the flywheel on your engine it has two seperate windings one for the charging of your battery and the other powers your headlights / elec magnetic clutch, the one for the charging will be unservicable these can be diffucult to access and test and is probably best done at your local small engine repair shop...
Hope this helps you out
Kind Regards

Hi, when it plays up try loosening the fuel cap. It is vented and may be blocked. Also the fuel cutoff solenoid in the bottom of the carby is renouned for shutting off sporadically. You can test this theory by removing the small sealing rubber from the tip off the solenoid and replace the solenoid if it fixes the problem. Hope this helps, regards Phil.

My guess would be that the crappy ethanol fuel we are forced to buy has clogged the jets in the carb. A good cleaning should fix you up.
I have fits with this fuel messing up my lawn equipment and my motorcycles.
