I agree with Chill in that the coolant temp sensor is suspect here. They can be tested (resistance values are in most manuals) and aren't particularly expensive.
If the sensor is failing and tells the computer that the temperature is higher than it is, it will make for some tough cold starts.
Also whenever symptomatic, it's a good time to review all tuneup hardware. Fresh Champion copper plugs, new plug wires, distributor cap, rotor, fuel filter.
