Can I assume that it feel's like a driveline problem ? One of the most common problem's is the rear transmission bushing being overly worn. What is the milage ?
Is it a manual shift ? If so the clutch may have hot spot's and in need of replacement along with getting the flywheel machined.

If you can feel the vibration in the gas pedal, especially when turning at slow speeds, ie starting off at a stop light or pulling out of a driveway and turning at the same time, the problem may be the clutches in the rear end. It is a well documented problem with Ford and a retrofit kit is available from your dealer. My 2000 Larriat rear end was just rebuilt under an extended warranty I purchased with the vehicle. Cost me my deductable only and the truck has never felt as responsive on takeoffs as it does now. Hope this helps.

I had this problem on my fathers 97 it could be the ignition wires is arcing to the block
suggestion: change wires and plugs or at least gap em (look for cracks or pits in the boots)
