your fuel system is not holding fuel pressure. the possibilities are:
fuel injectors are leaking- this would rresult in black sooty carbon build up at the spark plug tips;
the fuel pump check valve is no longer capable of holding pressure;
there might be an external leak along the fuel line;
the fuel injectors o-rings might be leaking around the fuel rail.
the fuel cap might be restricting airflow into the tank. if this symptom happens when the weather had been hot, then there is vacuum in the fuel tank that pulls the fuel in the rail back to the tank that would result in longer time pressurizing the fuel rail.

if you smell raw fuel around the car, that would be a result of an external fuel leak.
