Well, the first thing I would check/replace here is an inexpensive fuel filter. This sounds like the culprit. I know it doesn't seem like that would cause a sudden shutdown but they do. They get to the point where the fuel rail pressure can not be maintianed and the computer shuts you down (assuming it's Throttle Body Fuel Injected [TBI], or a Vortec, since you said "pour gas down the port"). The fuel filter is located on the frame rail just behind, or near there, of the driver's door. You have to get under the vehicle so I recommend heavy truck ramps at the least but prefferably a floor jack and jack stands. Its a round metal cylinder in the fuel line. Be careful removing the fuel lines from either end cuz they will spray or leak fuel and it always lands in your eyes. Line/hose wrenches are recommended and a backing wrench (to hold the filter from twisting your fuel lines into pretzels) is required. This is the number one cause of your problem with vehicles of this age. It's just a commonly overlooked maitenance item. Start there and cross your fingers.
