Fuel is fresh at each cutting, at worst a week old.
Sometimes a puff of black smoke and the smell of running rich when it stumbles.
I wouldn't say a large cloud of black smoke.
Thanks, Ed.

They may not have been tight in the guides when it was cold. How about when it gets hot?? No way to tell if the clearance was correct unless you ran a gauge through it. How did you clean the valve stem and guide??
It may be electrical, but I really don't think so. Could be a problem with a safety switch, making it cut out. Really don't think it's a mag issue though. Take the hood off and run it. That way you can see what the governor is doing. Could also be a sticky float/seat causing the carb to occasionally over-fill and flood. I know, really not much help, but not really enough info to work with.
