Why is my dodge journey acting like this??

So I my journey is having a hard time
starting, it putts and then makes a loud
grinding kind of noise then shuts off,
we try it a little later and it will do the
same thing except it starts.  It putts
makes that noise runs rich for a minute
then runs fine, can shut it off and start
again no problem. But then it sits over
night next morning trying start it, does
the same thing again bin having
