It's fouling out, but finding the reason may be a headache. The blinking is probably from misfires resulting in over fueled plugs.
Do you have anything done to the car? Only thing that I can suggest right now is to let it warm up a little before you shut it off. When it's cold out and it's in open loop, it intentionally runs very rich...just the way it is. Yours could be going to the extreme.
one possibility could be a fuel pressure regulator, but I'm not gonna give that out as advice since I'm running short on cash this week.
