There's no limit, but it sounds like your system is running low on resources while PD is producing. The quickest workaround would be to find a good spot to cut the video somewhere hear the 1:46 mark and use the Range Select tool to highlight that section then use Produce Range to produce just that section.

When that's completed, highlight the next section the same way and produce that. Bring the two completed sections on the timeline and use SVRT to stitch them together.

To figure out what's actually causing the problem, the best way to start would be to follow the steps in the Read Me Before Posting Guide and attach the DxDiag results so we can see how your PC is configured.
