If your leaf blower runs for 5 minutes then dies, it's likely due to fuel system issues, a clogged air filter, or a faulty spark plug. First, check the spark plug for signs of wear and replace it if necessary. Next, clean or replace the air filter to ensure proper airflow. If these steps don’t solve the problem, inspect the fuel system for blockages or leaks. Regular maintenance prevents such issues, so consider routine checks to keep your equipment in top condition.
