Yes, the signal to the PCM can be wrongfully perceived as low coolant, even if the car is full of anti-freeze.
The heater will stop getting hot when you're low on coolant. If the coolant is low enough the engine will overheat and it will be severely damaged.
If the oil is low in your car, it can eventually cause your car to stall and not start. It can also kill your engine.
If the car is starving for fuel or air (low power at idle), the car will stall while turning.
No, the only thing it would do is make the engine run hot. However, if the leak is large enough and low enough, the coolant could leak out fast enough to destroy the engine. You should get it fixed.
Is it low on Anti-Freeze? That is a known issue for a car to stall!
Low coolant or a defective sensor
Some cars have a sensor in the reserve tank that sticks or the sensor on the engine is gone. Get a manual for you make and it will show the locations.
From my experience, If your crank sensors bad the car will not start up at all.

There is a sensor valve located inside the reservoir its may be bad
It's a warning sign that you are low on coolant.
