My 7 keeps dying on me everytime i try to restart it. I have replaced the alternator and the starter and i have checked the battery and it's reading it's good. The thing is that every time I have to jump start it and then once i turn it off it won't start so does anybody know why? If anyone know please help me out ASAP

 

How does she idle once started? How does she run? Done anything recently that would cause a massive vac leak?

 

see she does everything normal but once i try restarting it she dies on me and well i can't start her up again.
