Help, loss of engine power and engine malfunction light

I've been out having some fun lately with my N54 coupe. However, there is an issue taking place which has me worried. Whenever I'm under full acceleration (wide open throttle) and go past 125-132 mph the engine power dies on me and I get the yellow engine light indication on the trip computer area. It has happened at different speeds within that range. Once the power shuts I wait for a while and the engine indication resets and the engine operation returns to normal (I have the new upgraded resistance JB4 installed). Has this happened to anyone else? I don't know if it has to do with engine misfires or if it is a top speed governor. Any insight would be appreciated.
