Get the engine warm, then open Real Time Mapping. Run the engine.
That will show if there are any compensations being applied

I hope I show the right thing

on the first picture is when my engine runs well

on the second picture it's after the engine is cut, he does not want to start anymore

the third image is when it does not work well, in degrade mode

It looks to me like the air temperature compensation is your problem. At 18degC it's showing +1% fuel at 22degC it's showing -100%

As Mr Drew says, that looks wrong.
Post a picture of your Air Temp compensations.

you have seen right

here is my air temp compensation
1.jpg
the -256 at 25 degrees seemed inappropriate, I do not know how he got there
so I replace it with -2

it seems to work, I'm not cut anymore
it no longer works in degraded mode

Thank you for your help, you got me out of trouble
I would never have found without you
