My diesel-powered car doesn't want to start but once it does, it runs fine. What's up with that?

I've got a 1984 Mercedes Benz 300D that for the last two days doesn't want to start but, after a few touchy seconds, runs fine. Right after starting, it seems like it isn't getting fuel or air or something. It just runs very wispy, in fact "gasping" is the word I want to use. I can have the pedal to the floor and it barely stays running.
Then, all of the sudden, it starts revving and running better.
Possibly useful info: we are in a sudden coldish snap (dipping below 30 F), the fuel is a few months old (more than 3 but less than 6), and I just had an oil change a week ago, before this started, and nothing was noted.
