ok i will post in english as it is easier for me to explain

the car start's ok then splutters and stop's restart again ok then 30 second's later it splutters and stops

i cannot keep it running with the throttle , i have changed the ECU , spark plugs and spark plug leads , fuel filter , Blue temp sensor , airflow meter , lambda probe , distibutor cap and rotor arm , cambelt ,

i have checked the fuel pump's and both still run well , when the problem is happening

i have checked at the coil (bobine) and it has a good 12v and a good switched earth from the distibutor

Please help or i am going to break the car as spares
