Why are my iPhone 3GS application screens shutting down randomly?

Why do the screens keep closing when I am inputting data or just reading a page in my different programs? It is so annoying. I will be working on something and boom the program just shuts down.

Any help is appreciated. I am using an iPhone 3GS, which is up to date.

    Before you reset to factory settings, be sure to check to make sure you have the most current version of iTunes installed. Also back up the data on your iPhone.

    Went to Genius Bar at Apple store. He said the battery was fine. Said to restore to factory settings, but I'm so afraid of losing all my settings, data, contacts, etc. How can I restore and insure that I won't lose anything,

    Try to restore your iPhone to factory settings and see if it helps.If this also doesn't helps,then it's a battery related issue which needs to be replaced.

    Some of the users have reported such issues and got it resolved by replacing the battery -

    In the link below,the author described that

    " After doing some deeper digging, I'm guessing that battery failure is the most likely problem."

    User Jhopk4 stated that -

    " My 3GS also began shutting off after I updated to iOS4. It got
    progressively worse. As you described, it would snap off with a ghost
    image still on the screen, no matter what battery % was. Worked like
    normal when plugged in.

    I took it to the Christiana, DE Apple
    Store and the genius confirmed a hardware issue by doing a clean restore
    of the iOS. He acknowledged he was aware of the issue, but refused to
    replace the phone or repair it.

    I removed the battery, cleaned
    the contacts, no improvement. The issue wasn't the SIM card or ATT
    network. I confirmed this by removing the SIM card, putting it in
    Airplane mode and then turned back on WiFi. In this (sim-less) WiFi
    state with battery, 3GS would still shut off. The phone always worked
    like normal when connected to power and never shut down.

    I
    ordered a replacement battery from iFixit. It is exactly the same model
    as the original, obviously a different serial number. It works
    FLAWLESSLY! Maps, GPS, games!! Like new. Period.

    Further
    research shows the problem is there are a few series of the batteries
    and the battery actually has a little circuit board on it that is
    apparently the cause (incompatible with iOS4) ......"
