All Colors go missing...

I am running a stress test on a block of steel with some inserts in it.  Not very complicated.  But for some reason when i add one of my inserts the the sim.  It still runs fine and even comes up with a chart and points to my max stress.  But takes all the color away from the model...  If i remove the block and run again everything is back how it should be with all colors in place!  What in the world is going on?  I am completly baffled.
