An Elusive problem.

[wannarace928]

My car as some of you may have read from previous posts, Has a problem we cannot figure out and before I take it to subaru later this week wanted to know if anyone has any other ideas as to what could possibly be causing this issue.

The symptoms:
The car starts fine with no problems. If the car is idle in Park and you rev it, it will rev to 5200RPM MAX and stall out. Then it is a bear to start a second time.
While driving down the road, you cannot press the gas pedal more than halfway down, if you do the engine will rev, but the car will not gain any speed, however it does not loose speed either.
If you rev it and promply let off the gas completely (say rev it to 4500 rpm) it will stall out.

What has been replaced:
The engine (with new cam & crank seals, valve cover gaskets, water pump, t-belt, spark plugs, timing belt idlers, accessory belt idlers)
The transmission w/4.44's w/Tranny cooler and filter installed
Torque converter was replaced w/tranny
Replaced MAF
Fuel pump
fuel filter
igniter
coil packs
ECU
TPS
and also tested Vacuum and fuel pressure

There are NO codes, no check engine light on, no power light flashing NOTHING!

Any ideas??
