hard to cold start

I have a 1988 190e 2.3
When the engine is cold, I have to let it run for about 3 minutes before shifting to drive, otherwise the engine stops. I t only happens
the first time I start the engine on any given day. Its been doing this since last june but it just got worse.
Any Ideas?
