    Sounds like a fuel issue.. I actually just replace the fuel pump in my GTP cause it would run until the car warmed up then just shut off and i'd have to wait a while and it would start again and run.. so far its good

    I recently had a similar issue.

    Car would start, but then shut off. If I pressed on the gas pedal it would stay on, but the rpm would jump up/down. Was driveable, but had powerloss and eradic RPMs. The issue was a broken (top of housing fell apart when removed) MAP-Barometric Pressure Sensor.

    Replaced it ($68) and all is good.
