    I would look into taking the Fuel Pressure reading using a Fuel Pressure Gauge when the symptom is occuring....
    Sounds like maybe a fuel delivery problem ....Weak,failing Fuel Pump.
    Low Fuel pressure could be causing a lean misfire.

    Thanks Frank, I edited your post to add it. Helps with search engine hits, but looks like Doc J has you on the right track now anyway.

    What should the fuel pressure gauge read?
    What is too high or too low?
    or what is the proper range?
    Thanks,
    Frank

    I show the fuel system pressure to be

    15 psi
    or really to be more specific, 14.5 psi for early manufactured 1991 shadows and
    39 psi for later 1991 thru 1995 built vehicles.
    So depends on when your vehicle was built

    I would venture to say yours will be the 14.5 psi one...if you have Throttle body injection...
    But make sure on the build date.


    Hope this helps
