1995 GMC Jimmy Four Wheel Drive Automatic 150000 miles

my jimmy all of a sudden started acting like it was running out of gas. i would push the gas pedal down and the truck would barley move.i took it to my mechanic and he hooked it up to computer and nothing came up, changed the fuel filter and cleaned the fuel line thinking maybe it was clogged. nothing has changed the truck and he has no clue what it may be. any suggestions?
