Engine stalls especially in cold weather or when the engine is cold. This is mostly when I'm just starting the engine. When run for a while, the engine performs just fine. Recently, the engine stalls even after running it for some time.

it sounds like a crank sensor if the vehicle stalls in any gear or when cold its most likely a crank sensor. located near the bottom of the engine. there almost always behind the balancer pully for the crank shaft
Cold weather has an adverse affect on batteries. The clicking sound could be from the starter solenoid not receiving enough voltage to energize the starter motor. The engine being hesitant to start and run could indicate the need of new spark plugs, wires, etc.
Be certain your cooling fan is coming on when the engine starts to get warm. If it is, then the most likely thing is the thermostat is sticking (either not working or only opening partially). Just follow the big hose from the radiator that goes to the top of the engine. It connects to the thermostat. They are cheap and easy to replace -- so, if it was me, I'd just go ahead and replace it. If it doesn't fix the problem, at least it rules out a big contender and there is value in that. Don
Most likely if it is temperature related you may have a temperature sensor that is failing. The sensor may not be reacting properly to the actual temperature and causing the engine to run rich in warmer weather when a richer setting is not required.
You could have a sticking injector or sticking EGR valve or a faulty TPS switch, all can cause a rich condition and a poor running engine.
Is the service engine light on or come on at some point?
I would start by having the car scanned for trouble codes. You can have the scanned at no cost to you at your local Auto Zone or Advance Auto Parts. Write the codes down and respond back.
There are two likely possibilities: 1) Old/cracked Ignition system (spark) is being shorted out by water/humidity, 2) Carburetor icing.
1) This test is more effective if done at nighttime or in a darkened garage, as any spark arcing will be visible. Start the engine and let it idle. Use a spray bottle with water and mist your spark plugs, wires, distributor cap, and ignition coil with water. If you see spark arcing or the engine starts to run rough or stall, there's your problem, replace the ignition component(s) involved.
2) If your problem only occurs during cold moist rainy weather (ie. 45 degrees or below), especially if it only happens during highway driving, you could have carburetor icing. There is a hose that runs from the exhaust manifold shield to the underside of the air cleaner housing. In colder weather a valve will draw heated air from around the exhaust manifold through this hose into the air cleaner to prevent icing. Either this hose is missing/disconnected or this valve is not working correctly.
The on board computer does not show the error code using the MIL (check engine light ) In my case the fault is in the crankshaft sensor. Had to get the car to a shop to read the OBD1 port to find the error. Replaced the sensor and everything is good. Found out a fault in the cam sensor will cause the same strange issue with the cruise light.
