Raving about Diesel Purge aside,  there is a whole series of other 
things that can cause this.  It is commonly described as 
"nailing."  Two of the most common causes, aside from crud buildup 
are a bad injection nozzle or a broken prechamber.  There is a little 
ball supprted on a pin inside the prechamber.  sometimes the pin will break.
