I had this exact problem with my 300D at Christimas time. I drove from Houston to the panhandle of Florida. Once I arrived at my destination and unloaded the car, I went to back my car out of the drive and experienced the exact symptoms you described. I thought at first it was the GP relay...no dice. It turned out to be the alternator. I ordered a new one, installed it, and have had no problems since.

The beauty of these cars is that the engine will keep right on running even after you have killed the battery and the alternator is dead. You may not have headlights or a radio any longer, but at least the engine still runs. (unlike a GAS engine!!!)
