My son's 91 New Yorker is having problems staying running when coming to a stop. It only does it occasionally, most times it will start right back up, but a couple of times he has had to wait 2-3 min to get it to start again. Sometimes he has to press on accellerator to get it to start again. Have checked fuel pressure, seems to be within normal specs. Changed crank sensor, and fuel filter. Had battery disconnected to chang power steering pump 2 weeks ago, and went through re-learn procedure. I checked codes with key on-off sequence, and only code that comes up is code 12, memory standby power receintly lost. I have read that this code should go away after12-15 starts. It has been many more than that and code is still there.
Please help!!

Sorry I forgot to say what engine. It is the 3.3 V6 engine. I have checked the vacuum hose at pressure regulator and am not seeing any gas. I went through and checked all ground locations that I could see and cleaned them. Also checked for vacuum leaks and am not seeing anything obvious. I tested my TPS according to my Chilton's manual, and all voltages seem to be within range. I do not have a vacuume pump to check the MAP sensor.
This seems to be kind of an odd problem, because it went from a problem with dying under acceleration to a problem with dying at stops.
