Default Engine starts to die a full throttle

Good morning. I bought myself a project boat and have an issue that maybe someone can help me with? It's a 5.0L mpi serial number 0W616784, we thought that it was electrical and may still is, not sure. Have done a complete tune up new cap, rotor, and wires. Runs great at idle and fuel pressure is 40psi at test port, but start to die off at full throttle, pull back to idle and doesn't stall its very consistent, when gauge starts to bounce at test port is when the issue shows. We are going to try alternative fuel delivery option today to see if it's possible that fuel pump might be falling off at high throttle, also have two injectors that when we pull power source off make no change to engine, they all test correct power as test. I hope someone out there can point me into right direction. Thanks
