My 2004 pontiac grand prix gtp has twice now thrown reduced engine power across my dash and acts like it cant get any gas and comes to a stop. Does anyone know what this might be the first time I figured it was because I wasnt getting anyt traction and my wheels kept spinning. Now it just did it out of know where. Will this happen if Iam not letting my car warm up enough?

I had this exact car and I had all the same problems your talking about, The pump although I can't tell you for sure is on the left side of the engine as your looking at it. If it is whining it is because it is low on fluid, also when topping it off fill it to the full mark while it is running. If it is foamy turn the steering wheel all the way left and all the right a few time to help get rid of the air. You may have to let it sit a while to let the bubble escape, check and do this again, it could be a bad pump also. The overheating problem I had with mine was a bad temp sensor for the computer. It has two temp guages and the computer uses on to activate the fan as needed. I also had another problem with mine, on the front of the intake is a small plastic elbow for a heater hose and this goes bad. Had to replace mine. Wasn't hard, and the part was cheap. Hope this helps you!

Have you ever had the catalytic converter changed. Over time the pellets inside will melt together and this will make the care very very sluggish like it does not want to run. You may want to try that.

Its the abs sensor, if you encounter an ice patch or snow you won't even be able to stop because the pedal will will push back and make the rip grind noise. If you pull the ABS fuse out, you won't have ABS but you can stop and you won't have the grind noise and back pressure for now. Its safer to not have ABS when the sensor is faulty.

Also not coming to a complete stop before changing gears will cause that as well.

I would start by replacing the Crank sensor and the cam sensor.
