Engine would start then immediately die, after a few attempts the engine would then start and run normally. It was found that when the car died the radio would not be on.

The turn signal switch in the steering column may fail causing the turn signals not to work on one or both sides.
The engine vacuum hose to the MAP sensor may crack resulting in a vacuum leak causing the engine to run rough and/or stall.
