I wonder if a vacuum hose is loose on the intake, because that will make the engine stall for emissions purposes. Did you do any service recently, like an air cleaner? Or was it out of the blue?

It just started out of the blue. Nothing has been done since I had new cats put on it just before the 80,000 mile mark. It has 105,000 on it now.....I will look around for a hose issue though.....

I had a problem like this on a 1996 Outback, again with no codes, and replaced the MAS (mass airflow sensor) - it never happened again. That said, I gave that same MAS to a friend several years later because the MAS on his car failed. He cleaned the sensor element and used it for two years with no problems at all. So, it may be that cleaning the sensor will resolve your problem....

2004 subaru keeps stalling...have to push gas pedal to get it started then when i let off...it dies...some days it goes just fine then it will start doing this again..also at times AT OIL TEMP light will flash when this is happening...seems like after car cools down, it will start back up with no problem
