The E39 M5 doesn't have an automatic transmission, so there's no such thing as "won't shift". You control the shift.
If loss of power was happening in an M5, you'd see a "Service Engine Soon" light come up on the dash. You can use a regular OBD2 reader or Peak tool to check the code and see if it's an O2 sensor, VANOS, or some other thing. If you have no SES light, then maybe it was disconnected or the bulb burned out.
I recommend taking the car to a qualified mechanic to have them diagnose the issue.
