Olds delta 88

I have a 1989 delta 88 that has taken to just caughing for a minute and then dying. If I let it sit for a while it will start right back up and run until it decides to do it again. It never used to do this, it ran perfect, any suggestions.

There is very little to go on here, but what there is suggests a fuel delivery problem, possibly a fuel metering problem. In light of the car’s age you may want to start by checking the fuel line pressure, to see if the pump is weak. That’s assuming you’ve changed the filter sometime in recent years.
