If the symptom is stalling when taking off from a stop when the engine is cold, that’s probably and air/fuel mixture problem rather than an oil temperature problem. The engine computer is supposed to greatly enrich the mixture (much more gas injected) when the coolant temperature is below normal operating temperature. Problem could be caused by faulty coolant temp sensor, but my guess, more likely there’s an air leak into the engine caused by a problematic vacuum hose or vacuum operated device. That weakens the fuel mixture, which is the opposite of what you need for a cold engine, and hence the stalling. Beyond a visual inspection, measuring fuel trims might provide a clue. The other common cause for this is a problem with the increase in idle speed function, which also is supposed to happen when the engine is cold.
