Small Engine Troubleshooting Problems? Ask a Mechanic Now.
What engine? Is the fuel tank venting, when it acts up, try loosing the fuel cap. Has fuel filter been replaced?
Once the engine stops, open fuel tank and restart. As Curtis said check fuel filter. If non of these work, when the mower dies, check for spark at plugs right after it dies (before it cools off) coil(s) may be getting to hot and stopping
What model Husqvarna is this ? Product number from label and I can search Husqvarna for all avail. info. I am a Certified Husqvarna Tech and Dealer, I can check any service bulletins on the product number and/or engine.
I would check the fuel cap. If tank does not vent, then engine will stall.
I see question is still open. Did you try loosing the fule cap?
It is loosing fuel, either from the cap not venting, or from the fuel solenoid in the carburetor, plugging the main jet.
