KA keeps on dying after a jump start

[J40sx]

Ka24e
1990 fastback
has around 59,XXX miles (original)
completely stock motor

My car rattles when i start it up, must be that infamous timing guide that is being chewed up, it only rattles for less than a second!

so my car myseriously dies at a meet.
I was there for about a good 1 or 2 when i go
to start up my car, it wont start, low battery
so i jump the car start right up, i let it run for a
while to recharge my batteries then turned it off.
When it was time to leave the car started, but as
soon as i turned on my headlight the car just dies!
So i had to jump it agian, only this time the car will
die, unless you keep adding gas so the idle won't drop
to zero. Finally i got the car home, and it dies.
so i went to get a new battery starts right up.
a month later the same thing happens
as soon as the car is jumped and the cables are taken
out the car starts to die after a minute or two.

i do not know the problem

alternator?

i need some help
