'93 S-10 / starts then stalls then wont start

I have a 1993 chevy S10 4.3 V6 2wd.
Most of the time I try to crank it up it wont start (turns over good), but when it does start it stalls within 30 secs or so. I will come and try to start again later in the day and the same thing would happen.

Could this be something as lil as a fuel filter? Or is it more the likely the fuel pump? Of course im assuming it is a fuel problem.



**update** upon further inspection the fuel pump is turning on, I hear it turning on when I turn on the key
