new plugs? what have you done maintenance wise lately?

Right off the bat I'd say look at fuel filter, air filter.

its a long shot, but I had a bad ground where the drivers side head connects to the body. I had the same issues. Check it out, it only takes a second.

check the PIP pickup INSIDE the distributor, just replace it. Does it do it all the time or when the car warms up?

I second the PIP sensor, either that or the TFI module.I have had 3 TFI modules go bad in 2 different Fords the last 3 years.When my PIP sensor went bad it would buck and revs would stop at 35-4000 rpm depending on load.
