93 Blazer - Problems Starting

Hello there. I have a 93 (full size) Blazer with 5.7 TBI engine. I drove the truck on Friday, no problems. Went out Saturday, it won't start. It fires, turns over, begins to start then stalls out. After that it only turns over, if it catches, it is only momentarily before stalling. My fuses are good and I have power to the pump relay. I can also hear the fuel pump when I turn the key to the on position. I've pulled my filter and it is not clogged. I've pulled my air filter lid off the top of the throttle body and after cranking the engine, I can smell gas so I'm pretty sure it's getting fuel. Any ideas or suggestions would be appreciated. Thanks.
