Husqvarna chainsaw

Has anybody had issues with a Husqvarna 240 chain saw ignition coils with a high failure rate.
Dad bought me a new saw in 2013, I added gas and oil to it, fired it up to make sure it ran ok.
Did not use the saw for about 6 months, next time I fired it up to use it, it only ran for about 5 minutes before the ignition coil went bad.
So I bought a new coil and put in it, thinking that I just got a bad one. Did not use the saw again for about a year.
Fast forward to yesterday, while using the saw hard for about 4 hrs, the coil I replaced went bad.
Now damn it, 2 coils with only around 1.5 gallons of gas ran thru the saw.
Ordered a new coil, it will be here Monday.
Is there something up with these saws?
I set the gap on the coil to flywheel to 0.010" using a plastic shim stock.
All coils were factory Husqvarna parts, this is starting to get expensive.
