When you loose fuel pressure , how much fuel on the tank? Below a 1/4 and you could be picking up air if the fuel tank pickup foot is broken . Been there , did the hutch mod, all good.

have you had the injector harnesses checked on top of valve covers either 2 per side or 1 per side this relays the info on timing and firing to each injector they are known to break down due to thermal and oil wear.. the code on injectors will tell a computer the injectors are bad due to slurry signal. this causes the injectors on either side to fire out of time causing power loss
