Infiniti Q45 goes out in P/N

Infiniti Q45 2001 reaching a temperature of 70 degrees centigrad every two minutes the car is turned off in p/n, start immediately and I do not have any fault code, the signal of the crankshaft sensor is not lost, nor ECM, someone will have an idea

I had a similar problem with a Sentra 01 SR20 Motor in Midworm was turned off in a time of being on, to this I mediate the generation of the air flow sensor and according to the manual it must be 1.3 to 1.7V in idle and this generated me 1.56 I put one of the vehicle one of another vehicle and this generus 1.38vy no longer went out. You should try your problem, the sensor that I put to try was a pathfinder 01 VQ35 engine I think it is equal to the Q45 and the sensors must be the same sometimes the cars are capricious and the cars are not causing and the manufacturer's specifications are not attached to the specifications of the manufacturer, but it is not more of knowing the specifications of the sensors to be able to diagnose a fault well.

Thanks I'm going to check on that side greetings
