i can be driving and hit 60 km/hr or 80 km/hr and the truck powers out or stalls right out while i'm driving kinda feels like it has the hiccups after a nite on the town -

Check your fuel filter for clogging. Replace it anyway if it's old or won't pass gasoline freely. -

replaced fuel filter, spark plugs spark plug wires and distributor cap and rotor and the chugging has gotten worse i hope it's not the map sensor or the torque converter... -
