Slicer skipping large Z segments...:\

I've got an odd issue, that will be more fully explained in pictures.

First up:  Using Repetier-Host v0.82b.  Using Slicer 0.9.7.  Slicing at 0.3mm

I'm modelling the four primary F-Zero race cars from the SNES video game.

The first two (Blue Falcon, Fire Stingray) were fine.  As I'm doing Golden Fox, I've run into this weird issue where Slicer will stop slicing at a certain Z-height, leaving a huge gap (see pictures).  Slicer doesn't complain about any holes, and 3DSMax STLCheck reports no errors.

Here is where it gets weird.  If I plate Golden Fox with my previous two models (or even one), it slices fine.  :\

Any ideas what is going on here?

(PlatedSliced.png is the correct slicing - it's hard to see with all the light blue lines, but you can clearly see the cockpit got sliced correctly in this one).
