    This proline has the 2 stroke suzuki, it will fire right up mow about 10 min. and just die like you were turning off a key. The plug will have a light brown discoloration and a little build up, you can clean the plug and let the mower sit a few min. and it will fire right back up. Anybody have any suggestions.

    After it dies, try putting a little gas down the carb and see if it starts up. If it does, then you have a fuel delivery problem. Maybe there is a vaccuum being created in the tank or there is a plugged filter.

    Use an inine spark checker and watch spark until it dies. If no spark when unit shuts down, replace CDI pak. If there was spark at shut down, check for non venting gas cap or debris in carb blocking main jet.
