Hello and welcome to JustAnswer!

There are many things that can cause the engine to run rough or die. It may be an ignition system issue, it could be fuel quality, an inaccurate sensor, it could be a wiring issue or a failure of the engine controller itself, or possibly an internal engine issue.

The first step in diagnosing the problem is to use a scan tool or code reader to see what fault codes are setting. Have you checked for codes?
