Hard Idle Then Dies

(2005 Buick Rainier)
in Paris, KY on March 04, 2011
My 2005 Buick Rainier has started doing a hard idle then it will die but no warning lights or anything will come on when this happens. What can cause this problem?

My first thought is that the fuel pump is failing. Check the fuel pressure.
Here's a directory list for you if you want a specialist to look at it:

Thank you very much. This is really aggravating because when no warning lights, check engine lights or anything come on in the car, it doesn't give me much to go on. At first I thought there may be a sensor that needs to be replaced but I never thought about the fuel pump.
