Some more description would help, does it fire at all when balking? Do you use both mags or only one when trying? And as John asked, does it do black smoke when it does start? Do you turn off the fuel valve when you make these stops? The first thing that came to my mind was the coils in the magnetos, shorting out when heat soaked. Both of them you ask, well yes maybe the condition that caused it worked on both coils. are the impulse couplings actually snapping when you crank hot? You might try opening up the engine side panels while you grab lunch, to see of cooling the mags helps or not.
