Screen freezing/non-responsive?

Have you had issues with your sd card not being recognized after a reboot? That has happened to me twice.

Nope.... not yet, anyway.

I'm having a recurring issue every single night where the screen slowly stops responding. I always notice it when I'm using the on-screen keyboard. I'll press a letter-key, and after a good 2-5 seconds with no screen input, it'll flash up the extended-characters menu as if I was hovering over the letter. Sometimes it'll just backspace over my entire line of text without me telling it to. After a bit of this, it'll eventually lock the touch screen up entirely, so that the only button that does anything is Power (which only serves to dim the screen off and on again). The only thing that fixes this is a battery pull. Not one or two or three battery pulls, either -- I'm talking upwards of 4-6 times before the phone finally starts to respond again.

I've already uninstalled a significant amount of applications and ensured that I'm running the latest software version. No difference. Other than a factory reset (which I'm beginning to sincerely doubt will achieve anything), do any of you have any suggestions/ideas for me? I do pay for full insurance coverage, and it's still under Verizon's warranty, too.

Does my phone need to be replaced, or is this a known issue with a known fix?
