Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

The engine starting and dying as you're describing is very often caused by a fuel delivery issue, but it's also possible there could be an electrical issue such as a bad crank sensor, an internal engine issue or exhaust restriction.

The first step in diagnosing the problem will be to use a scan tool or code reader to see if any fault codes have set. Have you checked for codes?
