I know this is not a true woodworking question – but it is woodworking related and I know the people on this website are some of the most helpful anywhere.

Yesterday I fired up my chainsaw. It started with a few pulls and ran strong for about 5 minutes. Then it just stopped instantly. I could not restart it initially. After about a 10 minute wait it started and ran strong again for about 5 minutes and, once again, stopped instantly.

It is as if once the chainsaw gets so warm something happens and it shuts down. Does anyone have a thought on what could be causing this?

Fuel line clog where it runs long enough to use up the gas stored in the line and then shuts off until fuel trickles back into the line, filling it.
(Blow out the fuel line real good and run a pipe cleaner through there if you can.)


Solid state and when he heats up, it expands enough to touch a shorted wire. Then it cools off enough to contract enough to start again.
(Check to make sure there are no exposed wires by anything else which could short them out, and make sure all your electrical connections are good and tight.)

Hope this helps.

Go to and look for the chainsaw forum and post your query with all the details including make, model, etc.

Your problem could be any number of things and until you specify the detail, you won’t get an accurate feedback.

One thing to look for is a plugged up gas cap, they need to vent air into the tank as gas is used up if they don’t replace the volume with air you get a vaccuum in the tank and won’t run. Easy to try, just loosen the filler cap and see if it solves the problem.
The other replys are also good possibilities.
