Brad, Turn the headlights on, disconnect the negative cable from the cars battery. Wait about two minutes then reconnect the battery and turn the headlights off. (The head lights are turned on to help prevent damage to electrical modules as it will temper the electric surge/spike when the cable is reconnected)
Try starting the car again. If you go through the sequence of car turning over trying to start then shut off twice and on the third attempt to start nothing as you experienced in your post #14 above.
Your SKREEM is not working properly. You can get it repaired from Needswings or Mercedes Swap Shop.
