My 04 z4 2.5 roadster is shutting down, and when it happens all the dashboard lights turn on, when im in a stop sign, and i suddenly hit the gas pedal slightly hard. I have to put it in parking, and turn the ignition on again.

Sometimes it does not shutdown, but when i hit the gas pedal slightly hard, the car does not rev, and then immediately works normally as it keeps running and going at a higher speed, then the music goes louder, as if the car automatically turns up the volume of the speakers.

battery is almost new.

any ideas?

thank in advance! my best regards!
