It's tough generating power from a pause, but there's no better way to develop explosive strength in the lower body. When you come up, make sure your knees angle outward over your toes. If they start to cave inward, reduce the amount of weight you're using.
If you find yourself tiring more quickly usual, take a look at your nutrition, as well as the quality of your rest. Fatigue in the gym can sometimes be a sign you're not taking care of yourself in other ways, so listen to your body.
