Hello all,
Has anybody had this same problem? I'd like to do a crossfade and some simple fadeouts, but my main source video disappears into the background, which breaks the illusion. I'd hate to be limited to only cuts in future projects. I'm using Boris FX Primatte, which is incredible, but in order to take advantage of its full capabilities, you've got to use it in custom compositing mode.
Thank you for any suggestions.

Many of the compositing modes in Vegas (and Photoshop) are luminance-dependent, which means if you change the "brightness" by fading, they enter the neutral zone with regards to the Composing Mask.
One obvious example of this is the Difference composing mode. There is a point during a fade of the compositing layer where the difference is zero, thus it disappears.
White bar over a fading background in Difference compositing mode: This is just one of many examples.
Experiment.
Do you mean that fade in/out will destroy Boris FX Primatte in Custom Compositing Mode?
If so, you'd better render the video first (or create nest project), and then add fade in/out for it.

This is exactly what I was looking for. Thank you!
Try doing a chroma key using Primatte on your primary source (your talent), but make sure that track (the track with the person in it) is set to CUSTOM in the compositing mode choices on that track. (custom is the only way to take full advantage of light wrap and blending modes in Primatte).
Now, do a fade out at the end of a clip on your main source while keyed over the background (the next video clip that's under it, usually), and the person will disappear, and you'll be left with only a background image mid-fade.
Note: fading your background at the same time will not correct the problem. The key is too fast and too sensitive.
But, as others have said, this is a limitation and inherent characteristic of chroma keying. You have to render it before adding any cross-fades if you're going to chroma key.
If the video events either side of the video event to which BorisFX Primatte has been applied and the pre/post video events do not themselves have Primatte applied, then place the pre and post video events on a track above the Primatte video event and apply the in/out fades only to the non-Primatte video events on the upper track. When using fades in Vegas Pro, there is no need to apply an in/out fade to video events on a lower track - transitions yes, but not fades/dissolves.
If all or most of your video events include Primatte, then the best option is to render each event off as an intermediate and use that intermediate on your project's timeline as suggested by @lan-mLMC .

Ooooh! This is good too. And it seems the least time-consuming. Thank you!
EDIT: I should have tead this morw carefully. I added an empty event about the entire timeline, but fade outs don't work like this as Primatte is post under it. Oh, well.
I won't be using green screen anymore. It's roo much of a hassle. When I pre-render the video inside Begas, it crashes immediately after saying I don't have permission. Nothing but problems with Primatte. I'm done.
Thank-you all.

This is related to the composite order in Vegas software.
Cross-fades is belong to the event level, and Custom Compositing Mode is belong to the track level.
Vegas always handles the event level task first, and then the track level task.
If you want to break this order, you must first render or nest the track-level tasks, and then import them back to Vegas for event-level tasks.
No more green screen for me. Too much of a hassle. Now Vegas tells me I don't have permission to play the clip back after rendering inside.
Screw it.
Thank-you for your suggestions.
