350Z TT goes SILENT mode!!!
OK i've been living with this issue for more than two months and now i need your help guys to find a solution for it.
After changing a head gasket, everything went ok the car was fine until the 1st WOT the car went in to SILENT mode!!! yes silent mode no sound for the engine and every single gauge in the car point 0 except the fuel pressure is 4.0 bar. As soon as i release the pedale it goes back to normal.
After some checking and scan tools i end up with noting the scan show no errors codes and everything under the hood seems to be ok.
So i sart changing old part one by one (fuel injectors, fuel pump, spark plugs, AFR and rearrange ECU harness) after changing these part the car starts normally but after warming up it starts misfiring. I thought to change the F-CON and start the car with my old friend UTEC and i did and the misfiring was even worse.
A week ago i sent the car to my tuner to check whats the issue and retune the F-CON. He change a cam sensor and tune it and got 570 RWHP on pump gas.
I received the car two days ago i drove it around the neighborhood it was grate. Today i took it out for a real test and after a few runs it suddenly starts to misfiring and wont responde to the throttle. And here i am stuck with the same issue.
Any suggestion on what might be the problem?
Thanks in advance.

Quick thing that comes to mind is that the car is going into limp mode and you have a really bad mis-fire... If there is a mis-fire still then there should be a code telling you it is a random cylinder mis-fire or that it is cylinder specific... Has anything changed on the car recently?

The very first issue you discribed sounded like your CPS but you would get a code for it. That used to happen in my GF's VQ35 swapped maxima while going WOT then it would go back to normal once I stopped.
