1994 Bravada Stumbling and Bogging?

Hello,
I own a 1994 Olds Bravada with the 4.3L and CPI. It turned over 90,000 miles last month and it has started to bog and stumble. I have been doing allot or research but would like an opinion of a good mechanic. Since it began I changed the fuel filter and noticed no improvements. It will stumble at take off and be fine until I reach my cruising speed (65MPH) after that it if I release the gas peddle, slow down a bit and press it again the stumbling comes back. I have read about faulty spider injectors and a bad fuel regulator. I would like some feedback if you have experienced this before I dismantle my system.
Thanks

I have tried 2 bottles of injector cleaner.

Yes, it could be a bad fuel pump, fuel pump pressure regulator..... sounds like fuel related.
