My buick stalled on me 3 diffrent times all about 4min apart,it would just die.it started back up aftrer couple trys.its like it not wanting to take the gas.

check the vaccum hoses on the booster

This could have several problems. #1 Fuel pressure due freezing water in fuel lines add thermal aid or rubbing alcohol . If you have access to a pressure gauge there is a service fitting on fuel rail that you can test pressure while driving and see if the pressure is gone when car dies this could lead to fuel pump electrical or more restricted lines. #2 intermittent sensor failure Mopar uses 2 sensors to control spark and fuel lose one could lose spark lose the other lose injection with a scanner they call it C/C sync ok (cam/crank) if no then check for each parameters for display.# 3 relay controls ASD and FUEL pump for voltage drops.

It means you injectors are clogging up (Sprays gas in motor) Go to parts store...Buy bottle throttle spray...not carburetor spray because it eats your rubber ceils up. Take the air duct loose from carb. While accelerating you gas throttle with your hand spray the bottle throttle spray directly into carburetor. As the car trys to stall let go of the spray...Repeat 3 or 4 times.......Ive seen the engine light go back off after doing this...It will get to your injectors and clean them...Ive done this alot myself and what a diffrents.Its works alot bettef that just adding injector fluid to gas...Promise

You need the exhaust converter so the O2 sensor can
work properly

It sounds as though the converter is blocked,as well
as the fuel trim, if that is correct term for an OBD1 System,
is not able to report back the oxygen in the failed converter

So the ecm can not provide the correct fuel mixture by
pulsing the injectors

I would also expect the timing chain to have a lot of slop
& possibly be off a couple teeth, from worm plastic gear
on cam

My 1987 buick centry limited cuts off when i drive but when i start it back up it will start right bacc up at times some times it starts and die agin but when it dies the battery light and service engine light comes on but once it starts the service engine and battery light goes away and dont do it agine tell it cuts off agine

you may not have the fuel lines sealed, they can **** in air without leaking fuel, especially in the tank, whre the pump connects

a bad fuel pressure regulator will cause this, the vehicle runs rough, the engine will not start (usually in the mornings) many times engine starts then stalls. a bad regulator can result in fouled spark plugs. also get it scanned to see if the crank or cam sensor is bad. if crank sensor fails there will be no starts. check these out.

THE ENGINE IS NOT AN INTERFERENCE ENGINE, REPLACE THE BELT AND U WILL BE OK.

Coil pack or mass air flow sensor.
