Sounds like your fuel pump is on its way out. Stay out of the upper rpms till you get a new one. $100 fuel pump is much better than a $1500 shortblock.

You don't need it just get a stock replacement.

I just read your other post in the fuel presure thread. You might have a bad injector that is stuck open. It would cause the same symptoms. Check for codes.
