1999 pltmouth Breeze

HI, I just purchased a 1999 plymouth breeze. It was sitting unused for approx 9 months. It was fine when I drove it out of the drive way. After driving it for approx 1/4 mile the radio stopped working along with the electric door locks. I noticed that the radio did come back on and at that time the door locks did work. A few hours later when I turned on the lighs I had no low beams the high beams where working. The car cut out at one point and then would not start after we pushed a few feet I was able to start the it. I also have no brake lights but have working tail lights and all of my flashers work. I previous owner did find a mouse in the car that was tryingt to make a nest. The previous owner thinks it is a problem with the condensation after sitting. There are no fuses blown accordingto my brother who does have limited mechanical ability. Any thought? Thanks, Pam
