Reduced Engine Power - S10 200CV

Hi,

I have done many of these S10 200CV 2.8TD, but I am with one here, which is causing me headaches.
No matter what kind of modification I do, after 1 minute and 15 seconds I work the engine, it appears reduced power engine on its screen.
However, engine works normally, with power and torque...

Did anyone see this before?
It is a manual gearbox S10 TD one.
I attached original.

Does it do it with the stock tune back in the ECM?

No, it doesn't.
Also, I tried to drive this S10 for some kms, but it didn't solve.
The stangest thing is that if I manage computer board, this message disappears. Then, if I turn S10 off and turn it on again, the message appears again after the same 1 minute and 15 seconds.
