I have not had that problem before, but from the service manual. Its.
Fuel Injector Group 2 supply voltage open circuit.
You have a fuel injector with high or open resistance or a bad ECM. The resistance for each injector should be around 185k Ohms +/- 10%. .

thanks for your help, cloned the computer into a spare one. Same thing.
All injectors are ok.
Found that when pushing the harness of the ECM near the AC line the engine shuts and produces the problem.
Cutted into the loom couldn't find a cutted wire... tapped it again and now driving 2 days witout any problem...
strange...

If it produces again I change the engine wiring harness because I am shure now that's the problem
