Fuel Pump, Grrr..... Options

[BluuFire]

So I was driving to a job interview when all of the sudden I push my A/C button and my engine revs drop to about 300 or so rpm. So i pull over and tried to start my car up again and the engine would crank but would not turn over. So I had to get my car towed to a local mechanic to have them look at it. They give me a call the next day and said they started it up right away and it ran fine. At this point I was really confused... I went to go pick it up earlier today and got it back and started driving away. I got one block away from the place and it died on me again so I got it back to the shop and he takes a look at it. He checked it over alittle bit and he says he thinks its a bad fuel pump.

First off, does this sound like a bad fuel pump to you guys/gals?
Also, if it is the fuel pump, what is the best brand to go with?

Any help at all would be greatly appreciated! Sorry, Im done ranting...It just peevs me when a mechanic looks over things that should have been looked at in the first place.
