Well perhaps George Jetson over reacted, but he has been trying to give you good advice based on what you have told him.
When your neighbor says fuel pumps and filters rarely fail, that is true depending on how you look at it. Pumps can reliably last 150k miles or so, but then start to fail with increasing frequency. My impression is that you have an old pump, and your symptoms suggest you are experiencing old-pump problems; however, the new information about code p1300 is important. Also, fuel filters 'rarely fail'; however, they become clogged with age and start to restrict the flow of fuel to the fuel rail, while at the same time increasing back pressure to the pump.
Code P1300 suggests a problem with your ignition (probably a bad electrical component or wire). I don't know the '94, so I can't help there.
