I'm still not quite sure what you're asking. If it's in park/neutral and you rev it, it stalls. When you're driving in gear it doesn't stall. Give it a little gas in park/neutral it's ok. Is that right?
Take a look at the Idle Air Control Valve (IACV). It also acts like an anti-stall dashpot when you let off of the gas. It could be dirty, clogged, stuck or just not working.
Assuming you have a 5.0, a common problem is for the screen under the PCV valve to clog. This forces crankcase gasses and vapors back through the hose that goes from the oil fill to the throttle body. (Backwards flow) This has a tendancy to clog the IACV with oil.
