Reset problem on my Axim

[AximDellDude]

My Axim has competely reset itself 3 times in the last 3 days. The first time occured after I noticed the power button switching from orange to green repeatedly. I quickly took the battery off and put it back on. A dialog came up asking me if I was sure I wanted to reset, I chose not to, but it did anyway. All data lost.
I reloaded and re-synced my apps. During an install, it locked up with some type of error so I did a soft reset. Again, all data lost, complete reset.
I reloaded again and backed up this time. However, when I was finished installing the Navigatin bar update from Dell, I chose to reset, and again, all data lost.
What is going on here?
Any suggestion is appreciated.
