Probably a coil breaking down under load. But there are 100 other possible causes like a gummed up injector. Or low fuel pressure. Or plugged fuel filter.

What “inners” has he replaced so far?

It doesn’t.  
My inclination at this point would be to put it on a scope, run the engine up, and see what’s happening with the ignition system. Has he done any diagnosis with analytical equipment?

Check the voltage at the coil positive terminal, low voltage could be causing the miss under load.
