Cadillac Repair: 1993 seville sts northstar 4.6 V8, seville sts, crank sensor

Question
The car started stalling few days ago.  It gave me "service engine soon" light. I took it to the mechanic and they told me that it gave bad crank sensors codes.  They replaced the crank sensors.  I picked up my car and drove it home.  The next day, it stalled again as I was backing out of my driveway.  I took it back to the mechanics and they told me that code p083 keeps resetting.  They told me it means "Loss of signal between crank sensor and ignition module". They suggested taking  it to dealer.  Can you please help.  What's wrong with my car?  What will it take to fix it?
