Vehicle was running fine then died. Now will start and run great until u let off gas and it dies almost immediately. I have replaced a fuel filter, throttle positioning sensor, and the fuel pressure regulator with zero change.

check fuel pressure It may be low. should be 9-11 psi auto parts rent gauge but you'll probably need an adapter to check it . also have ignition module checked and check wires on top of tbi unit for breakage.
