Is it a spark breakdown? When it no longer runs does removing a plug wire create a spark to the block when it is turned over? If no, how good is the coil, they act like you are describing when they fail, not allowing any power once hot. Do you have a way to test the coil? If you have spark and the coil is good then you have eliminated the spark side of the three legged equation. Air and gas are left. Sorry I cannot be more exact and you are in a very frustrating situation, but there will be an "AHA!" moment when the gremlin is found. Had one where it was a high rev failure and turned out to be the throttle linkage grounded a bare wire, it may end up being something strange, just keep at it.
Good luck,
