Are you running a standard heat profile on the barrel? or reverse profile? I have had instances where I wasn't getting it melted soon enough and causing blockages in the compression zone resulting in...

You could put an dial test indicator on your moving platen or on the parting line of the mold to see if it is blowing open during injection.
