Lumina 3.1 Mod 95 goes out after 1.5 min.

Good day:

I have a problem from which I have not been able to leave, it happens that a Chevrolet Lumina 3.1 mod. 95, the vehicle lights without any problem, but after 1 minute and 30 sec. Approx, it starts like coughing and turning off, it is heard that pulls air, if I try to turn it on immediately, turn on without problems, but the time mentioned and makes the failure.

Someone told me that it was a reprogramming question, and that I needed the original Lllave, but I don't have it anymore.

I hope someone helps me. Thank you.

Sorry, omit the important comments, the vehicle changed the oil pump, rings, connecting rods and bench. Before not towards the failure, it will not be a problem of calibration of aiming or something similar?

Already, the hoses are fine, the sensors and valves in perfect condition, to the Dys or Dis module, ok ... I find myself in a dead end

Good night <I ask ,,, if you teach it and at the time you take you can keep it teaching with a spray where the engine absorbs? And if it is asy, the problem is the key because in the key it carries the chip to test, if you do not have the key, in the key of the key it wears white wires in orange orange color buys resistances of different measures and the short ones and you are bridging one by one by one that turns on and voila
