This started happening on my trip home a few days ago. The first stall happened when I slowed down around a turn my car completely shut off, however the electrical power was still there. After I started going again it worked fine then I slowed down at the light and the same thing happened. The next light it was ok and then the final time I slowed down to turn in my neighborhood the car shut off again. We took it to the dealer and they replaced the EGR valve but it didn't work. The car seems to stall most when it is warm after driving after a half an hour. It immediately shuts off, no clunking, sputtering, etc.
Can anyone help me out on this? Thank you.

Hey Nick how many times do I need to answer this..... :-)
Without seeing it I would take a guess: try this run in the driveway at say 1500 to 200 rpm and then take the foot off the gas it may stumble. If it does the look at plugs and a device called a distribution block if it is dirty your plugs don't get the full juice they should. The last thing to look at on this age of a car would be the MAF meter which is the Mass Air Flow Meter and it sits on the intake into the manifold just after the air filter. they get old and dirty. The very last thing would be the Throttle position sensor.
These should get you headed in the right direction
Oh one more thing if the fix the shop said would fix it didn't take it back and get credit for the boobs not fixing it right the first time. I have had to do this and they act mad but realize in the end you are happy and they have a new customer..

wow im having the exact same issue with my 99 grand am...id love to know if you get this fixed and how. Ive been hearing lots of word to look at the idle air control valve. I took out mine and cleaned it off with some carb cleaner, but it didnt help-and it wasnt too bad looking to begin with. A tech at a dealership told me to just do a tune up to begin with, or "do the cheapest things first." I am afraid to take it to a shop because im a poor college kid and can't afford to pay for things that dont solve the issue. My car has been doing this for months and has stalled out on the freeway a few times in morning traffic-very scary! If you get this resolved could you PLEASE email me and let me know what happened? I would be so very grateful! Toxiccavies@yahoo.com

as crazy as it may sound, i used to have the same exact problem with a newer grand am, i went through alo of headaches for it, and my final rsolution was that after reaching 3rd gear, it then shifts into auto overdriver, the sensor that tells overdrive to kick, does not respond and the transmision does not down shift,so the car dies, and when you turn the key back on the sensor is reset, so it is no longer in overdrive, that is why it occurs when you are slowing down

Could be a number of things,sounds like your iac valve.(idle air control solenoid)Not giving the engine air after you release the throttle completely.Just a guess,but if it starts &runs fine right after it sounds like the engine is not getting air.You could try cleaning your throttle body & valve & try that.Have a tech do it though,as i do not know how mech inclined you are.If no resolve after this,take it to a good shop & have it diagnosed.Good luck

i would say it is the camshaft sensor it happened to me on my truck one time like it just shorted out and then was fine but i replaced it anyways cause it is hard on the engine when it does that. for me it costed under $100 and took 15 minutes for me to do it myself and that was for a big truck so i am sure it will be less for your car
