Question: 83 Cadillac Coupe Deville codes 4.8.8 & 0.7

when I press the Warmer and off buttons 4.8.8 and then 0.7 comes up and the Service Soon and Service Now lights come on. I been having trouble with my car stalling after driving for a while, it will lose RPMs and if I let up on accelerator then press down on it sometimes it will continue to drive, other times it will stall and I have to wait to get it to start up again. Please can someone tell me what could be wrong?
