1996 6x6 big boss 400 2 cycle fouling plugs at 10-12 hr run time like clock work
filter is clean
most of the hrs are low gear under heavy load at lower speeds
runs good never has problem until you shut it off and go to restart, as long as its running its fine
plug is always clean and dry but it will not start until i put new plug in it, fouling may not be the right term as much as just burning the plug

any thoughts?

Running a K&N filter and outerwear will flow more air and possibly keep it from fouling plugs. I would personally re jet the machine for your particular use. This will keep you from fouling spark plugs.
