Engine turns off when transmission is shifted into gear?

Hello,

So the vehicle will start up just fine but when you put it in drive the engine shuts off?

When you start it up, does it idle rough?
Is your check engine light illuminated?

This issue could be triggered by a number of reasons. It could be sensor for the engine management system, it can also be a vacuum leak.
