Do you have gears and/or a cam? This is a pretty common "problem" with a lot of modified 5.0's. Shift down when it starts bucking, or if in 1st or 2nd get the revs up. It's really hard on u-joints when the car bucks like that.

Did you change the fuel filter?

Maybe a spark promblem. Mine used to do that until I gave a full tune-up.

Dump the codes and see what the computer says is wrong…

Here's the link to dump the computer codes with only a jumper wire or paper clip and the check engine light, or test light or voltmeter. I’ve used it for years, and it works great.

See http://www.troublecodes.net/Ford/
OR
See http://www.dalidesign.com/hbook/eectest.html for more descriptive help
OR
See http://www.mustangworks.com/articles/electronics/eec-iv_codes.html

Trouble codes are either 2 digit or 3 digit, there are no cars that use both 2 digit codes and 3 digit codes. Codes have different answers if the engine is running from the answers that it has when the engine isn't running. It helps a lot to know if you had the engine running when you ran the test.

distributor would be my guess , I chased a problem like this for 2 months , pull the distributor and check for play in the bushing and make sure it spins freely ......

This might seem like a stupid response, but maybe its your clutch? I know mine will buck because of the clutch if it gets to low in the rpm band.
