First off, when I start my Taurus, the RPMs usually jump up to 1500+, I'm not sure if that has anything to do with my problem or not. The main problem I'm having is that my car will start and run fine for a while and then it will just die while I'm driving. It seems that most of the time it happens when I am letting off the gas (coming up to a light or going down a hill). Then if I wait about 30-45 minutes and it cools down it will start back up. I took it in and they said they were having problems getting it to stall out, they finally did and said it was a faulty fuel pump and was gonna run $1000+ to fix possibly, which seems pretty steep. Anyhow, it doesn't seem to me like this could be a fuel pump problem since it only seems to happen when the car gets warm. The problem has happened on nice days too, I drove it for a while on cold days and the car didn't die. Any help would be much appreciated, thanks in advance.

It is a bit much to replace the fuel pump
check under hood for vacuum leaks
check IAC valve remove clean and or replace
after it stall on you have to be ready to test the for fuel and fuel pressure
also check for spark

So it could possibly be a fuel pump problem? I don't see how the engine temperature could affect the function of the fuel pump. That could be due to my lack of mechanic knowledge though...would $850+ be more reasonable or is that still seeming high? Thanks.

5 to 6 hundred is more like it to be fair

a couple of things I would try are replacing the throttle position sensor or the crankshaft sensor.
