    sounds like the fuel pump has failed. have it checked to verify.

    Possibly a bad distributor cap and rotor. If it gets worse when it is damp out I would be almost 100% sure thats your problem. Your looking at about $20. You may have a bad fuel pump. Check fuel pressure. When you hit the gas the car demands more fuel so the fuel pressure may not be there to meet the demand.

    start with your fuel filter and fuel pump relay before spending the money on a fuel pump.
