Yep
Nope
Blown head gasket
It can if the cylinder fills with coolant.
The most common cause of a blown head gasket is an over heating engine. Low coolant or coolant not circulating through the engine causes the engine to heat up and the gasket to fail.
Yes. There is coolant flowing through your heads and if that gasket is blown then coolant could be entering your cylinders, causing stalling. Check your oil, if it is "Chocolate milky" looking, then you have coolant entering your oil, possibly from a blown head gasket or many other locations. Hope this helps. Remember to start with the simpilest solution first.
