Help Browser restart plz help

[JM4N245]

I own a AT&T Xperia Play that I have rooted. Ive have just recently rooted it a couple months ago. Just thought that was important to mention. This problem just recently started happening and I dont know how to fix it. Everytime I open up the browser I can only be on it for a minute the it gives me an error and then I cant reopen it based on that error. Then if I click the power button to turn the screen off it restarts itself! Can someone please help?
