Why does my old Craftsman mower suddenly shut off when I am mowing?

I have an old Craftsman riding mower, 42" cut, 6 speed, Model LT-1000-161COVH that shuts off while I am mowing. Sometimes it will resume mowing after setting awhile. I have taken it to a lawn mower repair service and they cannot seem to find the problem. Can you help?

The mower shutting off can be an inconvenience and keep you from getting the lawn trimmed. I did some research and I was able to find two links that will provide you with some good information. I hope this helps while you wait for your expert response.

Next time the engine starts to die, loosen the fuel cap for ten seconds. If the engine smoothes out, I recommend replacing the fuel cap. The fuel cap has a vent that should allow air to replace the used fuel. If the vent is plugged, fuel will eventually stop flowing from the tank. The fuel filter and the fuel pump if your tractor has one could also cause the same issue.

If you do not think fuel is not the problem, you have to determine if the engine has spark. To check the engine for spark remove the spark plug wire and insert a screwdriver into the boot. Make sure to hold the handle of the screwdriver and position the exposed metal portion of the screwdriver close to something metal on the engine. A bolt head will work well. Then try to start the engine. You should see a spark from the screwdriver to the bolt head. This mean the coil is good. If you do not see a spark most likely the coil need to be replaced. If you see a spark the problem is most likely fuel related. I hope this is helpful. If you need further assistance, please submit more details.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
