mustangbullittgt

I have a 2001 ford mustang bullitt gt with a 4.6..it lost all power and it stalls out when you rev on it. it don't over heat. i replaced the IAC and the cats on the driver side. but i can't get it to do more then 25mph. And it trys to stall out. I'm lost on what to fix on it next and i need my mustang running like a champ again. i also replaced the fuel filter.
