for starters i have a 2001 Intrepid 2.7L with approx 110K after about 25 to 30 mins of speeds between 45 to 55 it shuts right off ,when you try to start it acts like it wants to but won't. If you let it set for an hour or more it usually fires up after some cranking. Has anyone else had this issue i've been thinking possibly a fuel pump or filter but i know the filter is built into the fuel pressure regulator. Also will not go over about 3K rpm when reved up. I have replaced cam and crank position sensors but no changes.
