It could be an intermittent electrical fault like a loose connection somewhere or a reg/rec fault that's happening when it gets hot but just because you've got full power at the upper end of the revs doesn't mean it's not starved of fuel at the lower end so I wouldn't rule out a fuel supply or carb issue yet. When it starts how's the idle? When its not starting have you ever taken out the plugs and tested them for spark? Or checked if they're wet or dry? Another thing to check when it's running is the temperature of each header by throwing some water on them and seeing if they dry at the same rate. If one dries slower than the others it points to that cylinder having the issue then you can investigate if it's a fuel or electrical problem
