I would say probably not the alternator... if it almost stalls the car 
then it is putting out. (unless bad diodes and putting out AC...) I would 
check for a draw first. Takes ten minutes with a DMM at the fuse box to 
find which fuse has a load on it with key off. THen check to see whats on 
that circuit.  First check: Trunk light!!!!!
