Locate the fuel pressure regulator and remove the vacuum line and start the engine, inspect, if vac port leaks fuel , replace regulator, provided your vehicle is equipped with a vacuum operated fuel pressure regulator.

SOUND LIKE YOU HAVE A STOPPED UP FUEL FILTER.

Hello. The GMC Sierra has an electric fuel pump so you should ensure that its fuses and relays are working before checking it. You may need to clean your fuel pump or replace it if your gas tank is not empty, but your vehicle has difficulty getting fuel. The GMC Sierra comes in a variety of styles and trim levels that can affect the replacement fuel pump you choose.

My 2000 Grand Cherokee had the same problem, without all the sputtering, it would just die approaching a stop. We could only keep it running by slightly pushing down on the gas petal when coming to a stop. I replaced the Throttle Position Sensor, but that didn't change anything. A new mechanic I found replaced the Idle Air Control Valve, and we've had no problems in a week.
