Coming down a steep mountain I put the car in 3rd. When I put it back in drive I got this message. Can you tell me if this is dangerous or costly?

Here lately my 98 Cadillac deville has been running a little hot, today I let the car sit all day from 9am- 2:30 pm. I went to pick my kids up from school and the coolest temp reached 212 pulling out of the school I reached 35 mph and the car shut off on me completely. The Windows won't roll down the ignition won't even attempt to turn over. My battery is good head lights and everything works but car won't start. Any help is greatly appreciated! ! Thank you
