...because as the load increases, so does the cylinder pressure and an increase in cylinder pressure causes an increase in resistance across the plug gap. So, if you have a weak ignition component, it will be stressed more under WOT.
I wouldn't feel it's tune related since you don't have a camshaft, unless something got really fat fingered.
The only other thing I would consider is some sort of fuel cut (limiter) or TQ management. Possibly a loss of speed signal causing the cut, but you would normaly get other codes with that.
