New Fuel Pump?

About a month ago my engine wouldn't start well and it would take about 10 key turns before the engine started. This kept on until last week when my engine wouldn't start at all unless i put my foot on the gas and helped put gas in the engine. Well the bad part is I'll be going about 40 down a road and shift out of gear into neutral to stop at a red light and my rpms will drop anywhere from 1000 all the way down to 200. I would rather it be high than low but it's scary when I can feel the engine break while I'm rolling. But then when I completely stop, the rpms go right on up to 800 (idle). Would a new fuel pump fix this or is there something else I can do about this?
