The engine cuts off at high RPM unpredictably. It will work for
days or weeks, but shuts off and takes awhile to start every now and
then, usually when I am doing Interstate driving. Then it is fine for
another while.
I had the fuel filter replaced recently and it still does it. When
I am trying to start it, I hear the fuel pump working during the two
second interval when I turn the key to On.
It has never cut off during city driving.

Any ideas? Thanks.
