Answer
Rhonda,
If your transmission is leaking fluid, you first need to take care of that.  If your transmission lacks fluid, you will experience hard shifts.  That can also cause acceleration and even starting problems when the engine is cold.  This can also cause your stalling problem due to the fact your flywheel may not be able to turn properly because of lack of fluid.

Have any leaks fixed, and make sure the transmission fluid level is appropriate.  If fixing the leak does not help, have your transmission inspected at a transmission specialty shop.
Good luck!
