Pep Boys doesn't really tend to screw people over. I'd trust them if I were you.
But I'd question on why temperature increase is caused by the fuel pump - that doesn't sound right to me!

Some newer cars actually don't let the engine rev high if the car has overheated. If you've got a temperature problem then you're best bet (if you're sure that it's full of coolant and water and there are no leaks in the system) is to replace the thermostat. I hate those things because they cause so many problems so often. It's normally a quick fix and doesn't cost much. That's what I'd try first. You're problem doesn't sound like a fuel pump problem right off the bat. It might be that you have two problems, overheating and a bad fuel pump, but first make sure that it's not just the thermostat, as it's the cheapest thing to replace.

A thermostat will not cause a car to stall. Especially not 1/2 way up the temp gauge. If the thermostat was really bad, the engine would overheat, and if you kept driving it in the red zone, maybe I could see it "stalling" but honestly by then the engine would be toast.
A fuel pump that is going out, can indeed work well while cool and then start loosing power as it heats up. I'm not saying the diagnosis is definitely correct, because I don't know if they checked things like fuel pressure at the rail, and, if they tried a new fuel filter first, but the fuel pump does make logical sense.
If it were my car:
1. assuming the fuel filter wasn't just replaced, have it replaced. it should be done about every few years/30000 to 50000 miles, depending on how you believe. a plugged one will make the pump work really hard, heating it up.
2. check fuel pressure right after a failure (stall) if at all possible. if low, its the pump. if not low, i'd start thinking about electrical issues like coil packs instead of fuel.
Good luck!

A thermostat will not cause an engine to stall, it only controls the flow of coolant within the engine. You say that the gauge only goes to half-way so that would mean that the thermostat is opening fine and not causing overheating.
The fact that the stalling occurs when the gauge is at halfway is irrelevant.

You should take it to a REAL mechanic that will scan it and check other things on it. Fuel pump is only a possibility at this point.

I would say it is just a coincidence on the movement of the temp gauge. Pep Boys has mixed reviews but in general are good mechanics

i tell you what i would do.i would change the thermostat(for all it cost) and then see if it still does it.you wont be out very much by changing it and who knows,it might take care of your problem,but iam kinda like the others said,a thermostat wont make your car stall.sounds more to like its fuel problems,like gas filter.

take it to the dealer and have a professional diagnostic test done. they will tell you exactly what is wrong without the guess work. usually cost about $75 for this but if you start replacing parts just guessing what is wrong you can easily spend several hundred and you may still never find the problem.

Neither.
Take it to a REAL mechanic.
