A little out of my league here, but I am currently working on a 1963 28HP Johnson which, I believe, has some similar characteristics to your motor, so here goes:
(1) Does the motor have a ‘kill’ switch/button? If so, is it engaged?
(2) Does the motor have that annoying fuel efficiency contraption? If so, is the linkage between that and the throttle set up properly?
Other than that, I remember hearing somewhere that ‘bad’ coils will work for a while and then crap out once they warm up. But, if that were your problem, I suspect that the motor would have quit sometime during your initial 20 minute test.
About the only other thing that I can think of is that perhaps your initial run loosened up some crud in the carb or the fuel tank and said crud is now plugging something up somewhere in the fuel delivery system chain.
The prior suggestions are probably better than these, but I thought I would throw my 2 cents worth in (1 1/2 cents accounting for inflation).
Good luck!
