How long have you owed the truck?
Did you work on it recently?
This sounds like some plug wires are on the wrong cylinders.

hi spike

thanks for your reply and to answer your question i have owned the truck for two years and for the plug leads when they get changed they always get numbered before removel and refit.

Ok, then I would start by having the ignition timing set properly.
Then check the vacuum advance on the dizzy to make sure it is working properly and that the vacuum advance vacuum line is in good nick.
