308 cranking and stopping after running

Hello dear friends. I have a 308 1.6 HDI diesel allure 2014 model vehicle. Since 1 month, the vehicle has been taking it smoothly when I start in the morning, but it stops after 4-5 seconds. post full torture. I start for 10 minutes by keeping the starter pressed for 10 seconds. It pretends to work every now and then, but the cycle drops and stops again in 1 second. While such work continues, it starts suddenly and there is a sound like a sbap from the engine, that is, it works a click more loud than the normal diesel sound and it cuts off and returns to normal after 5-6 seconds. after connecting to the device. But the tool strangely does not throw any errors in the memory. They said we will send the injectors for revision, the problem is probably there and it will cost 2500 TL or something. One day, as soon as he got out of the garage, he stopped in the first gear, I got him to hit 2, he pretended to work, but when he pressed the gas, it was as if one of the spark plug cable was pulled out and he did it that way, again 3-5 seconds later. If anyone has a problem like this, it makes sense to take it to Kaya Pejo and see it or take it to the authorized service, I passed all of them. After all, he does it not every morning, he does it one or two days a week and he does it only in the morning, he does it for hours when he's off for a long time. Thank you very much in advance for your time and information.

Get well soon master, I do not understand much about the vehicle, but as the master said, the injector is not spraying enough. They said expensive in terms of price because not all injectors are defective. While the vehicle is running, use an injector cleaner for 5 minutes over 3,000 cycles. Maybe the diesel filter or the pipes carrying diesel to the injector may be clogged. If this economical method does not work, then put the enectors to the test. Replace only if there is less spray, no need to replace them all.
