1999 Oldsmobile Silhouette Oldsmobile Sihlouette Backfiring

Engine Performance problem
1999 Oldsmobile Silhouette 6 cyl Front Wheel Drive Automatic

I have a 1999 Oldsmobile Silhouette when I turn it on it idles fine but when I try to accelerate it backfires. It will die and then I will have to sit there for a minute or two before it will start going again. I get about 10 miles down the road and it happens again. It has the worst problems trying to go up hills.
