Fuel lines?

I had some trouble with my 98 GT starting so I replaced the fuel filter and I had it running fine for a while. Then the other day I was coming off the highway and it stalled. When i tried to start it nothing happened. I had about half a tank of gas but it seemed as if there wasnt any fuel getting to the engine. I pushed it a good distance and managed to get it started again about an hour later. I havent had any problems since then but it still makes me worry. Any thoughts on what it could be and what I should do to take care of it?

It happened again! I started the car up, then it stalled and wouldnt start after that. I had to put it in neutral and push it to turn it around and then it finally start. I thought i was on pretty level ground so I dont think that had anything to do with it. Please help me!

Yea at this point I have narrowed it down to only the fuel pump. I know my inertia switch isnt acting up. Unfortunately I dont have the money to replace it right now so I am going to ride it out until it becomes a more common occurrance. Then I will have to bite the bullet and swap it out.
