I have a 2004 Pontiac Grand Prix GTP. The AC/Heat
The fan relay is stuck. It is a relatively inexpensive part. Your owners manual will tell you which relay it is and where it is located, most likely under the hood. Once you locate it, pull up on it to remove it and then take it to an auto parts store to get a replacement.

I have a 2004 Pontiac Grand Prix GT that doesn't
It could be the ETC sensor (electronic temp. control) which send a signal to the computer to tell the temp. and how to mix the fuel to the throttle body for start up and during the day. This switch looks like the engine temp. switch on the heads but they are not the same. The ETC is usually around the thermostat outlet not in the heads or intake. Just be sure you are changing the correct one. It is not hard to change, you may loose a little antifreeze when you remove it but it you are quick you can screw it right in and if you want you can drain the radiator down a little and then install it.

Reduced Engine Power and then died
If it does it again go to a auto parts stor and ask them to put the scan tool on it and get the codes pulled. Write them down and post them on here. You may be able to get codes now. It probably stored the codes in the cars computer.
