problems with cONTOUR

Hi, I own 1996 Ford Contour. I has been an okay car, but recently, the sunroof, died out. How can you fix that? Then sometimes, when I drive, the car stops, in the midddle of the road and you have to turn it back on and have to do the transmission again. That is preety unsafe, becuase, I can be on a highway and the the car stops, and it cause a muti vehicle crash. Please help!:banghead:
