What could be the problem

What is your question?

I was driving when all of a sudden I wasn't able to give gas and my car was acting as if it was going to cut off at any minute as I was on a busy street. I had to make an emergency pull over because it had actually stopped. As I tried to re start it again., it would start but wouldn't kick over. I'm being told by non-mechanics that I need a new fuel pump. could that be the problem.?
