Could be a few things. Got any vacumm/air/exhaust leaks anywere? What is fuel pressure set at? Any black smoke or anything like it may be running to rich? Could need some need spark plugs/wires, maybe coil pack. I not to good at the hesitation/running rough stuff over the internet. Just thought I would throw some ideas at ya until someone more experience gives you some ideas. Not much help, I know ...Nick.

I had a similar problem that got progressively worse and it was the catalyst in the catalytic converter melting and restricting the exhaust flow. It may be something to check and it is nothing the handle of a large hammer will not fix.
