I had a similar problem. My 50hp force fuel pump is operated by a vacuum line to the crankcase. The Vacuum line was old. When heated up I would loose vacuum and loose power.

i put in new fuel pump kit today and it is running great without elevating the tank.diaframs looked stretched but no holes in them.took me a while to get new springs in right places because old ones flew off as i disassembled the pump.no instuctions with kit either.thanks for the help.
