The second one I have owned that the non drive side crank loosens while riding, I see some were recalled but mine has a different serial number, anybody else had bother with these cranks?

Got them on one of my steeds, right as rain.

It's almost always the LH side that loosens where a crank is held on with a bolt in the end of the axle, because left cranks suffer bending and torque at the same time. Right cranks (where not permanently fixed to the axle, as yours is) tend not to loosen, because they drive the chainring directly. They suffer from bending and torque loads 90 degrees apart, never at the same time.

I've just fitted a pair to my new build. They came off a redundant frame I had hanging up and I never had trouble with them on that bike. You need to torque the bolts up to 11-14Nm and a standard Allen key won't do that.

Yep 40
It's a really beefy thread on the Gossamer. I tighten by hand until it feels firm and that seems to work for me. No evidence that the bolt has loosened at all over time. That being said I do remove it reasonably regularly to regrease the BB as otherwise it starts clicking and creaking like every other FSA BB I've had.
