  If your Makita Trimmer engine stops quickly or doesn't reach full speed, start by warming up the engine adequately. Ensure the choke lever is set to "OPEN" if the engine is already warm. Also, check the idle speed and adjust it if it's too low. A clogged fuel filter (replace it) or a dirty air cleaner (clean or replace it) could also be the cause.
