X2 check fuel filters.

Also clogged fuel tank vent could cause those symptoms.

Easy to check by stopping and opening the filler cap when it happens, see if it has vacuum.

update....... i just notice today that i can drive my car allday at slow speed no problem at all. but the gas pedal still feels like it should be more power. but on the freeway at high speeds theres no power it acts up like it wants to stall.

i'd replace the fuel filters; remote possibility that the catalytic converter is plugged

update yes.. it was the fuel filter i change it and had the catalytic conveter check from a muffler shop its good thank you for the help guys.
