    How old is your fuel filter? It seems to that a clogged filter would do something like what you have described.

    What does this mean ..not trying to be smart or anything just wondering??

    Usually fuel related if no light..but run it long enough you will get a light.
    Hard to diagnose a vehicle these days without a code .
