Well Bruce, I think you are right. Though there is still a good chance you have a bad fuel pump, I would say the odds are greater it is the filter, given the circumstances you describe. Matter of fact, now that I put a new filter into it and she is running well, I am pretty certain of it, but don't count your chickens yet, for as we both know, Murphy of Murphy's Law, sits on your shoulder like a parrot sits on a pirate's shoulder.
