Yes, I believe it should idle with MAF unplugged, I have seen guys running their E46's unplugged for weeks but again, I do not know the 2003 4.4 system to give you a solid answer. I would look towards an intake leak somewhere in the system causing the stalling but get the new MAF installed and go from there.
E46 and an X5 with a 4.4 are two different animals. One is a V8, the other is an inline 6. A common intake leak on 4.4 engine is the CCV at the rear of the intake manifold.
