My 85 chevy truck won't start when it is cold, unless I put it on a charger. on 1990 Chevrolet 1500 Pickup

My 85 chevy truck won't start when it is cold,(sits for 2 or 3 days) unless I put it on a charger. I have had the carborator worked on and replaced the battery and the fuel pump. It turns over fine but it doesn't fire at all until I charge the battery or kick it off. Once it starts it runs fine,What could cause this unusal behavior?

Have your alternator checked. May be going bad and producing less power than is needed to recharge the battery fully causing a slow drain of power in the battery till starting the vechicle cannot be accomplished.
