won't let me unlock, won't stay on long enough to let me try, won't reboot

This happens intermittently. Sometimes I tap on the screen, turn my phone on, unlock and use... No issues.

Other times, the phone won't wake up long enough to get my very short unlock code drawn on the screen before the screen turns black again. During these times the screen is unresponsive for the tap to wake up bit. So I have to push the power button on the front of the phone.
Sometimes, if I am SUPER DUPER fast putting my code in, it will still turn off, but when I hit the power button again to try - the phone is unlocked and I can use it. Other times, it won't work at all.

When it is in the middle of one of these moods, I also can not turn my phone off to reboot it. Nothing works.

I go away for a while, and suddenly it allows me to use it.

Why is it doing this, how can I stop it. I have 9 more months on this phone I cant be getting a new one yet.

I would try to do a factory data reset
