It ran good for awhile when you replaced the fuel filter? Sounds like you've got a messy gas tank. I would put a filter between the tank and the fuel pump and get another metal fuel filter up front. Keep an eye on the clear one at the tank to see how quick it dirties up. Blue has this write up on how to do it, Z Car Tech Tips Fram G3 Filter Installation

It is typically fuel as above but if you rule that out then it is usually distributor/timing

Thank for the input guys!

Think I figured it out, the rear filter was disgusting, I replace it let the car run go 20 minute and took it for a test run. She pulled great right threw the problem area and beyond. I'm gonna keep my eyes on the filter to see of fast it gets dirty. Hopefully I don't have to clean out the gas tank. Thanks again guys couldn't have done it without you. -Nick

Gas tank's not all that bad, thanks to Blue again. Z Tech Tips Ball and Socket Compression Rod (AtlanticZ.ca)

Uh Oh! It says ball and socket but it's the tank renewal.

Take the sending unit cover off, under the spare tire, and see how cruddy the tank is, 1st!

Will do thanks man

Take the sending unit cover off, under the spare tire

Wrong, wrong wrong, it was my bedtime! That cover is under the spare tire tool kit. You'll lift out the fuel gauge sending unit, about a foot deep.
