Could be a bad timing chain I guess, but if the chain is bad, when checking the timing, the mark will bounce around with you. First thing I would do is find a known good distributor to try and see what happens then. If it does it then, more than likely you have some chain/gear problems.

When it does this, how does the truck run?
