I asked him again today,he has ecu tune,he told me when this thing started,he uploaded a different ecu file,and when he put it the problem disappeared...Then like 1 month again the same thing started again...

Sounds like the processor is loosing its NVROM like a battery connection or battery power to the ECM, The processor flash is not sticking, can be a bad ECM.
What chip and interface is he using?
