If this only happens after the car has set for a while it could be the fuel pump relay. The fuel pump relay only closes for a few seconds to pressurize the fuel rails. After that the operation of the fuel pump is controlled by the oil pressure switch. If the relay is inop the engine will have to be cranked long enough to get the oil pressure above a certain level. I know someone that this happened to. Once the car was finally started it could be shut off and would start normally.
