I had similar issues with my 94 S-10 pick-up 4 months ago. Ultimately, it was the fuel pump & sending unit. Same situation as you, certain days it would run fine, start numerous times throughout the day and the next day, would not start. I was actualy glad I had the pump replaced when I did. As it turned out, there was a hole in the top of the tank and replaced all 3 components. Now it starts everytime.
Keep your fuel tank at least 1/4 full to keep your pump submerged constantly.
