Default 4.6 cuts out at high throttle

my 4.6 2001 stang used to run fine. now it's as if i got bad gas or something. when i try to romp on it at all, it cuts out and just will not take off and scream like it used too. it has bbk lt and off road x pipe, cold air and bbk power plus throttle body on stock motor. i put it togethe ra year ago and it ran fine. now i just cant do anything with it.

This may sound stupid but is your traction control on?

Plugs, coils, coil boots, fuel filter, air filter. Just a few things that could use tune up.
