Its indication towards faulty fuel pump.The pump has low pressure.Its taking time to flow fuel to the engine.---------As per your problem mentioned, it indicates the problem with fuel pressure.-------- The fuel pressure is low.---------- First thing you can do is get the fuel pressure checked, this will confirm the problem. --------- If the pressure checked low that means problem is with faulty pump and clogged fuel filter. -------- But if pressure checked ok, then fuel pump relay has to be checked.The relay is actually not faulty, sometimes relay gets hot and stops functioning. So it may show proper voltage if checked by meter.You try bypassing the relay with a jumper and checked.If the car, starts runs properly , that means relay is faulty.After you by pass the relay, drive the car few miles then wait for 10 minutes, then again start the car, if it starts that means relay is the issue.Replace the relay.The fuel pump relay located in engine compartment fuse box under the hood.------------- But if problem is same as before after by passing the relay, then relay is not the issue.----------

If the fuel pressure is checked ok, then other possibility is faulty o2 sensor and crank sensor. The o2 sensors are before and after catalytic converter.-------Both the sensors are to be replaced.------ And as per you mentioned your problem, its quite possible that faulty o2 sensor will cause this problem.------ O2 sensor is the part which sends signal to ECM( the cars computer).It sends signal to computer about fuel / air mixture.How and when to send fuel to engine.--------- If o2 sends stops sending signal to cars computer then it will not send the fuel to engine.------- In your case the o2 sensor is getting overheated and this is stopping the o2 sensor from sending signal to ECM.But when your car shuts off the sensor gets cool and again it starts working.------ So as per problem, get both the o2 sensors checked and replaced.---------- Also get the crank sensor checked.------------- Also get the throttle body and IAC valve cleaned.------ The idle air control valve is also located at throttle body.Clean both throttle body and IAC valve with throttle cleaner.--------This will help.Thanks.Helpmech.
