Car won't start

My car won't stay running, I ave replaced fuel
pump. And filter. I'm getting plenty of pressure out
of the valve. It will start every once in awhile for six
or seven times. When it does start it will idle high
as it lowers the idle it gets to just about normal
idle then shuts way down an starts sputtering.
When I attempt to give it gas it just bogs down an
you can hear it sucking air....... I'm lost
