Hi,
The most common cause is a failing crankshaft position sensor. When it stalls, does it start right back up for you? If it doesn't, we need to check for spark at the plugs when it doesn't start.
Here is a link that shows how that is done:

Also, take a look through this link and let me know if anything mirrors what you experience:

Let me know.
