Husqvarna is crazy about micro switches [Swedish nanny state]. I had some starting/running issues with a Husqvarna, solved it by deleting most of the "safety" micro switches. How are you to let the engine cool down by running at idle if it cuts out with a seat switch? Get off to open a gate and have it shut off? Stupid.
That may sound out of date, old school, but years ago, we had to use our brains while operating equipment.
Dumbing down makes people stupid.
Ride that ball.
