Cadillac Repair: car quits after five miles of driving, memory reset, e52

Question
I've recently bought a used 1992 deville with a 4.9 motor. the gentlemen that I bought it from said he was coming home from vacation. when he hit a bump and the car died soon after. he restarted the car, but he could only go about 5 miles before it happened again,and again. HE had the car look at ,but found nothing wrong.So, he parked it. If I did the codes write they are E47,E51,E52 and F32,F48  Do you have any thoughts? bought the car for my daughter to drive. Thanks for the help. Darin  

Answer
E47 = BCM (computer) to PCM (computer) data transfer problem.

E51 = NO such code.

E52 = PCM memory reset (caused by battery being disconnected.

F32 = PCM (computer) to BCM (computer) data problem.

F48 = Refrigerant system problem.


What you need to do is CLEAR (erase) all the codes and see which ones come back.
