When you type an email You can save a draft by tapping the word cancel in the upper left corner and an option to save draft or delete will pop up. Select save draft.
I assume that you mean that the apps are crashing and that the iPad is not shutting off on it's own. If you use an app and it crashes it takes you back to the home screen. If the iPad totally shuts down, the screen turns black and you cannot wake it by tapping the sleep button or the home button.
If apps are closing or crashing, try to download any free app - restart the iPad and see if that helps keep the other apps from crashing or closing. If it works you can delete the app if you don't want it.
Try closing apps. Double tap the home button to bring up the task bar. All of your recent apps will be across the bottom. Tap and hold down on any app icon until they all wiggle. Then tap the minus signs in the left corner of all of the icons in order to close the apps. Tap the home button twice. Then restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up, hold the sleep button until the Apple logo appears.
You could try resetting the iPad as well. Press and hold down on the sleep button and the home button at the same time for about 10-15 seconds, until the Apple logo appears - ignore the red slider.
If the iPad is totally shutting off - it could be time to restore the device.
