Alternator/Belt Problems

My problem is the car loses electrical power when the engine is operated any way other than idling or mild everyday driving. At first I though it was the alternator, although the alternator, pumps, belts, etc are all brand new. I replaced the alternator as well as the belt and the problem did not stop. The serpentine belt also seems to develop a mild chirp once the motor is warmed up. Is the problem with the belt, tensioner? Any other suggestions?
I am at a loss and extremely frustrated
Plz share wisdom with me
