1997 Chevy Cheyenne Not starting

I drove about 50 miles. Stopped for about 2 hours and started truck again. It just sort of sputtered and died, then it would not start again. It turns over, but seems not to be getting any gas. I can hear the fuel pump humming (?) when I turn on the ignition. There is a faint smell, does not exactly smell like gas, more of an ether type smell (?). It was sudden. I have never had any hint of a problem with starting the truck or the way it runs. Please give me a couple of suggestions if you can.
