P0101 is a MAF problem. First thing I'd try is cleaning the MAFs. Check electrical connectors too.

2013 Sport with G3 CAI and Fast Intentions CBE. Same issue. I literally had it down to a science last year.

1. Start car instant limp mode
2. Shut car off and wait 45 seconds
3. Start car - no more limp mode!
No limp mode when going to work in the am, but always in limp mode in the evening when leaving work

This went on for months until I got an actual CEL.

Took the car in was told the CAI was to blame. Dealer calibrated the MAFs and I haven't seen the issue for almost 8 months now. Fingers crossed

My 2014 Nismo has done this twice. Cold car in A.M. no codes, oil temps good, both times I had a 1/4 tank of gas and the tank of gas previously was not my normal gas station. Noticed it doing 30 to 40 MPH. Was like driving an old 4 cylinder car where it took 5 miles to get up to 85mph. Other then K&M air filters car is Stock. I opened gas cap and reinstalled, but probably just a coincidence as I also turned car off. It's at the shop for that, single clicking noise from rearend with rubbing/drive line/rear end whine. Also showed them the front suspension bushings melting from the extreme heat under and in car. I also gave them copies of the hub/CV axle service bulletins and asked them to see if the EVAP SERVICE BULLETIN addresses the intermittent loss of power. They said it will take them a week or so to address. I said no problem as long as it's fixed, under my extended warranty. Otherwise I will fix the rearend issue and install upgraded/aftermarket rear assembly.
