Check Engine Light and Low Fuel

[ouhockeyplayer]

So today I noticed that my check engine light was on while I was moving the car. I have not drove the car in a few weeks because of a lot of snow on the roads, but I have started it in the mean time. I believe the light has been on since the last time I started the car as it stalled out on me while running in the garage one day. It has never done this before so this is where I assume the problem started. The car seems to be running fine now and does not stall. What do you guys think. I called on star and they were having technical difficulties and could not run a test. Could it be the low gas in the tank and cold temps? I haven't been able to get it to a gas station because my driveway is on an incline and it is very slick right now. I would never get the car back into the garage if I took it out.
