99 pontiac grand am charging problem!

My father has recently bought my sister a 1999 Pontiac Grand Am SE for her 16th birthday and right off we have a problem. The car when jumped cannot hold a charge for more than 3 1/2 minutes w/o dying. We have replaced the battery and had the alternator checked, and both are "GOOD". Now the problem is that when we can only start the car twice with the new battery before it is dead. Does anyone know what the problem is and how to fix it?
