Ford: Ranger pickup,starts when it wants to, ford ranger pickup, ford ranger

Question
My son has a 1994 ford ranger pickup truck.Four cyl. engine.He lives in Arizona.Lately he will attempt to start it. Turn the key ,engine turns over will not start. Goes out a while later, starts right up when the key is turned.Does not stall when driving,but has had it run like it is starving for gas. Could it be the fuel pump ? Filters ? Has happened a few times over the last few months.Any help is appreciated.He has a new family .Not a lot of money.I am not there to help. I'm in Wisconsin.Hoping it is something he can repair.
Thanks,Larry Matuszewski

Answer
Larry the next time this happens what i want you to do is have him with out starting the vehicle up is cycle the key to the on position wait 5 sec and do this 5 X  then try to start it if it does start then the fuel pump is going bad.  let me know .
