sounds like a fuel problem or a vacuum leak, i would check the engine compartment for any loose hoses, if the car dont stay on though its going to be hard to do. check fuel pressure, if your under specs probably a bad fuel pump or restricted fuel filter, the fuel filter is located right above the differential in front of the fuel tank. what kind of maintenance does your car get, have you ever had your fuel injection system cleaned, try replacing the fuel filter and running some fuel injection cleaner in your gas. but try diagnostics first before you start spending money.
