Because of your concern (and I would be concerned as well) that the breeder's male gliders keep dying, I would take your little feisty girl in to a
glider-knowledgeable vet for a wellness check. It's possible she has something physical that is causing her pain and distress. Only a vet can properly diagnose and treat, of course.
How large is her cage? Sometimes you'll see gliders running circles in a cage that is too small. It's a combination of stress and boredom. Here are some links that may help explain some of her behavior:

Here’s our page with
bonding links, if you haven't found it yet. The key is to go at her pace, not yours. She needs to get used to you—your scent, your voice, your movements. Because she's already showing signs of fear and stress, it's best to start with the noninvasive techniques. Wear fleece scraps and then put the "blankies" in her pouch to sleep with. Sit by her cage and talk to her, or read a book out loud. After she's gotten used to your scent and voice and doesn't crab or try to lunge and bite when you approach her, then take her out during the day while she's sleeping and wear her in a bonding pouch. She first needs to learn to trust you, and associate you with good things. Be prepared to have lots of time, patience, and love (and treats) on hand to form a lasting bond with little Wynn. Tent time always helps with the bonding process. Here's a good link on that:
Critter Hill tent time. You can pick up a nice tent at places like Wal-Mart or Target or a sporting goods store for around $20-$30.
Remember to let her set the pace. The good news is that she was once deeply bonded to a different human, so there's great hope that she can transfer that love and trust (once you earn it) over to you.
