Cydia opens, freezes, then won't load

[onsenk]

Hi there,

I'm wondering if anyone has some advice - Google has failed me on this.

Cydia will open and work fine for a few minutes, but then freeze up. If I exit, kill the app, and relaunch, I get a blank application with no content (photo attached). After some time, cydia begins to work again, only to repeat the cycle.

Anything I can do to fix this? Thanks.
