Hi,

There are many things that can cause this to happen. This vehicle is really new to having such problems.

Does the check engine light stay on when the engine is running? If it does, then you really should have the computer scanned for diagnostic trouble codes. The stalling could be the result of an emissions-related component that is still under the manufacturer's warranty.

Here is a link that explains how it's done:

If you don't have the scan tool needed, most parts stores will do it for you free of charge.

Next, if the is an engine vacuum leak, it can cause this as well.

Here is a link that explains how to check for a leak:

Let me know if you find any leaks. Also, if possible, have the computer scanned for codes and let me know what they are.

Take care,

Joe
