Having fuel issues

I’m new to this whole forum and I’m sitting here having trouble with my 04 mustang my fuel rail doesn’t have a Schrader valve to check actual fuel pressure I’m just going off my scan tool which says I’m receiving 10lbs of pressure I’ve replaced the fuel pump and fuel filter already the pump is receiving 12v and I’m stumped the car will start and idle no problem at all it’s after I give it more than like 30% throttle the car will bog down and shut off it’ll turn back on no problem and idle I’m just stumped on where to go next
