94 PA Cutting Out

My 94 buick park ave is cutting out too while driving just started doing this a couple months ago. I took it to my regular mechanic but he couldn't find the problem. I then took it to the dealer and they had it for a week and could not find the problem. The car only has 70,000 miles on it. I certainly can't sell it the way it is. My battery is 7 years old. And certainly should be replaced. But could that really be the problem?

I'm going to have the dealer replace the ignition switch....I'll let you know if that solves the problem.

the dealer already ruled out the ignition switch. Now I'm stumped! If Anyone can help please post a reply.
