1991 Chrysler new yorker fifth avenue turns off at stop signs?

I have a 1991 Chrysler new yorker fifth avenue and i've had plenty of trouble with it in the past. Recently there was an electrical problem not letting the car start at all. that got fixed but now when i was slowing down to a stop light the "check gauges" light came on and my oil level went down to the lowest point and the car turned off. i was able to turn it back on but it has happened more than once. any ideas?
