In most cases, a vacuum leak will not cause the engine to stall while driving. It can when at idle or initial acceleration, but once you are moving, that is unlikely the cause.
To me, if it stalls once you are driving, my first thought is a fuel issue or a failing crankshaft position sensor. Take a look at this link and let me know if anything mirrors what you experience:
So, if the battery is weak, we need to take care of that first. Is it possible for you to have it recharged? If you don't have a charger, most parts stores will do it for you.
Once that is taken care of and the starter properly turns the engine to start, I need you to try something. See if it will start if you use starting fluid. If it does and then stalls, we know it is a fuel-related problem. If there is no change, I need you to check for spark at the spark plugs.
Here is a link showing how to check:
Try this and let me know what you find. Also, let me know if you have other questions.
