No power.

BUMP

This first happened to me two weeks after I purchased the Z four years ago. I've been driving for about 30 minutes so the engine was warm. I stopped at a red light, but once it turned green, there was a significant loss in power. The car didn't stall or anything, but the throttle response felt very flat. I pushed the gas pedal to the floor, but the car barely accelerated. I pulled into a parking lot, turned off the car, started it back up, and everything was back to normal. So odd. This happened maybe once every six months, so it didn't really bother me.

Fast forward a few years, and my car sat in the garage through the winter. Once I took the Z out for a drive last week, the same symptoms appeared. I didn't think too much of it, as the problem always went away almost immediately; all I had to do was shut it off and turn it back on. This time, however, the flat throttle response did not disappear until the third time I turned the car off and on. Whatever it is, I'm pretty sure the ECU is reading a soft trouble code, that's why the problem disappears when the motor is turned off and turned back on. My question is, what component could be the culprit? It happened when my Z was bone stock and it's happening now with the typical breathing mods. Any ideas?
