Sounds like it may be vapor locking at that rpm. But if it's only doing it at that mph it sounds like that trans isn't down shifting like it should. How many miles are on it?

Put it on a code reader. Save a headache! Sounds like fuel delivery is cutting out. Could be o2's, fuel pump/filter issue, or poss a computer like TPS, IAC valve, maybe ECM... Like I said, find a good garage with a good diagnostic computer.
