Golf R APR stage 3 fuel problems!!

I have an MK6 Golf R down here in UAE which we I did APR stage 3 GTX turbo upgrade for the car and he is suffering from the following problems.
The car drives normally most of the time except when he is cruising slowly it suddenly starts hesitation as if there is an insufficient fuel delivery to the car and it looses power for a certain period of time but eventually it comes back to its normal power levels.
The car is equipped with the following
1. APR HPFP
2. APR LPFP SYSTEM
3. APR INTERCOOLER
4. APR RFD
5. APR GTX TURBO
The fault code which is appearing on the VCDS is P310b.
We recently replaced the following.
1. Injectors
2. APR HPFP
3. Low Pressure Fuel Pump in tank.
4. 155bar rale valve sent from APR

The problem is still occurring and the code as well.

Have you checked your coil packs and sparks?

Did the APR HPFP comes with a new thrust sensor if not I would replace your thrust sensor on the high pressure pump as that fault appears to be related to the failure part.

I change everything in the car even the G410 sensor and I don't think the Sparks need to be change because the car is same time it's opening boost

G410 fuel pressure sensor is on the fuel rail. Did you replace the sensor on the HPFP?
