Another issue to keep in mind is that a traditional import will also truncate 10 bit ProRes files to 8bit. So you are best trying to pursue the AMA solution which is unfortunately giving you issues.
Can you forward any additional details such as the structure of your drives and hardware? How was the ProRes file generated?
Is this source material on a pocket drive or still on CF media or etc? Have you tried copying local first, if so? Are you working in a project which matches the native frame rate of the ProRes file?
Sounds like some sort of system resource issue. Are you on a 64 bit OS?
What is the error message?
Is there a reason why you are transcoding now?
You could just work with the ProRes material via AMA to at least start cutting. If your PC chokes on the stuff you can work via draft settings until ready to finish.
Wonder if a video mixdown or transcode of your timeline would have the same issue.
We've seen stuff like this before but we are lucky enough to have multiple machines and usually it will work on another.
