Thank you for contacting Husqvarna's Answer Army.
The most probable cause of a unit dying after just a few minutes of operation is a clogged fuel tank vent.
On your trimmer, the tank vents - to let air in as the fuel is used - through vents in the fuel tank cap. If the vent ports are clogged with dust/debris, as can happed over time, a vacuum will develop in the tank, preventing the carburetor from drawing additional fuel. Replacement of the tank cap may be all that is required.
However, be aware that a dirty fuel filter, a pin-hole in the fuel delivery hose, need for carburetor adjustment, stuck piston ring, or engine wear from long-term use in dry, dusty conditions can cause the unit to exhibit the same operating problem.
If it does turn out to be more than just the fuel tank cap vent being plugged, you should have the unit evaluated by an authorized service dealer.
