Interesting you got yours to work (VMWare 6) - mine's never worked since I upgraded to 6. $50 upgrade down the drain, no workable support, no one can reproduce it or track down an issue from my logs. :(

It helped a little but still crashes for me. I have the same issues with VMWare latest version.

Does suspending the VM help you?

Sorry to reply to my own message, but I just found this [1] where the recommendation is:

"I managed to fix this by going to the Virtual Machine Settings, clicking Advanced, and then checking the "Pass power status to VM" checkbox."

Haven't tested extensively, but I haven't had a crash in the past day.

Thanks! I will try this and let you know.

I have to quit VMWare Fusion or run the risk of spontaneous reboots while it's asleep.

It does. No crashes if VM is not running.
