Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

In order for the engine to start and stay running you need good spark to the spark plugs , injector pulse and good fuel pressure. In order to be able to help you determine the cause of the engine stalling you need to check each one of these thing and determine which on you are lacking, if you can do this and post back with the results I will try and help you find the cause.

what does that relay do
Expert:  Ron replied 1 year ago.

The relay I assume you are referring to is the Auto shut down relay which control power to the computer and the ignition system , the next time you loose spark, run the test steps I have enclosed in the link below and see if this will help you narrow the problem down.
