89 bronco ii problems

I have a 1989 bronco ii and it has problems running.

Usually it will start right up. But after I drive around for 5 minutes or so and I let up off the gas. It just suddenly dies. And I was at McDonalds the other night and I had to keep my foot on the gas at the drive through so it wouldn't die. But after waiting for 10 minutes it died anyways. And then I have to wait roughly an hour before it will start up again after that.

I just got the battery replaced today and it's still doing the same thing.

Any idea what the problem could be.?

How does the vehicle idle after you start and run for 5 minutes. Does it run rough or just idles low. If it runs rough, you might have a tune up related problem. If it idles low, you will need the idle control valve cleaned and even replaced. Good Luck.

it idles low. would the idle control valve cause the vehicle to just stop running once I take my foot of the gas? and when it begins to die it sounsd as if the vehicle is running out of gas.
