Welcome to 2CarPros.

It sounds like a bad distributor ignition control module. It is located under the coil packs. I can't guarantee that is the problem, but they symptoms match.

I attached a picture of the component. You can remove it and have it tested at a parts store, but if it isn't hot, it will most likely test good.

Let me know if this helps.
