I agree very strongly with the timing issue...among many others, my truck had the same problem when I bought it...
Other items to check:
The mil disrtib cap is prone to tracking and can cause similiar problems. Point gap and condition should be looked at as long as your in there with the cap.
Fuel filter could be nasty if its old and the trucks been sitting a while...also the amount of fuel the pump is moving...it also has been a problem for several poeple that the 'sock', the screen in the fuel tank, melts over the years and gums up the pickup tube to where ya cant flow enough fuel to run properly.
