you should check your battery cables first and make sure they are tight. then if still losing power check the connections going to your alternator. What you probrably have is a lose connection somewhere, so tighten everything you see.. :)
A power loss can be from a dead or almost-dead battery. If the car loses power on a hill, it might be a fuel injector or fuel pump, if I'm not mistaken.
If a car shakes and loses power when idling it can be the spark plug. If a spark plug is fouling, it can cause power losses.
