If you have an air block, you should see black unburned fuel (black smoke) at the exhaust.  Will it rev up in neutral?  Is this a DDEC controlled engine or all mechanical injection?  You may want to place a piece of clean hose in a five gallon bucket and connect that to your fuel pump and see if that makes a difference.  If it powers up then, you have a blockage or air leak in your fuel supply hose.

Let us know.

It does Rev up in neutral but it does so kinda lazily.
We gave up for the night.
In the morning I'll check that the throttle is going wfo and if that checks out I'm pretty sure it's got to be low fuel flow/pressure. 
I'll see if I can rig up a tank and maybe a pump and see what that does for power. 
I still have to find the air leak and now the problem with the lean to the passenger side.
It should be a whole lot easier now that I can get a jack and jackstand under her.
