    Usually when the fuel supply gets low, it does that so my guess is the same, either injection pump or lift pump.

    There was a post a few months back I think it said put some ATF fluid in the fuel if it gets better then it's the injection pump?

    Well do a search, go back 6 months.
    I would do the search but I am at work and a little busy.
