I have just completed an KORD-EDDF flight with the PMDG B77L in real-time (~8h) with FSXWX running all the way without any abnormality.
Although it does not exactly match your problem description, maybe, you can have a look at the 'mysterious' P3D-PMDG-after-several-hours-freezing phenomena, which is not fully understood yet, as far as I know.
Actually, I was affected from this issue, too. However, reducing the MESH_RESOLUTION to 21 and TEXTURE_RESOLUTION to 25 (default values) helped (... which could be pure coincidental because it is not explainable).
Here is some information:
