A couple months ago it happened where i was holding rpm at 5k on the highway and the car cut power for a moment but the engine didnt cut off it just ran at lower rpm after this i was able to drive in fast situations no problem until last month it happened again and now twice this week, Where Im slowly climbing the rpm in gear and the car cuts power for a moment, I htought it could be the tank being too empty but the last time this happened, today, the tank was full. Any idea what this could be? also no lights on the dash. My car is a 2009 g37x coupe. Every time the issue happens the car runs fine its just a momentary loss of power sometimes but it is getting more frequesnt.
