ERTYUIO keys stop working many times throughout the day

Question

Every couple of minutes, the “E”, “R”, “T”, “Y”, “U”, “I”, & “O” keys on my MacBook Pro stop working.  It is driving me nuts!  I have found a way to get them to work again, but it involves typing a bunch of random keys until those letters appear again.  Then out of nowhere they top working again. I am typing this in TextEdit, and am finding that they are not dropping out at all, which is very cool to find out but I did need to begin this question with a bunch of random letters to allow me the use of those letters in the first place, so this application is not immune to the problem, it just doesn’t seem to activate the problem. 
Here are some things to know:
Aftphpptptptpehpouqerptuorqneptuoqretptrehpehpqetter typing a bunch of random letters really fast, it will work again.
The issue seems to begin in Safari.  I just went to Safari to check some of the settings and when I started back up in TextEdit the letters weren’t working once again. 
SAFARI PREFERENCES:
It doesn’t seem to matter whether I have auto-fill on or off, letters drop out with either setting.
I have Sticky Keys on OFF and Slow Keys on OFF.
Bluetooth is not activated.
I use compressed air to clear dust out from under the keys.
This problem is SO F-N ANNOYING!!!!
Does somebody have any idea what could be going on and is there any way to stop this annoyance?
I have a MacBook Pro with system 10.7.5 using Safari 6.1.6
Thanks!

That is very strange. I can think of no software issues that would cause the " “E”, “R”, “T”, “Y”, “U”, “I”, & “O” " keys to get wonky and only those keys.
I'm running Mavericks here on my 2011 MVP 13" and Safari occasionally loses the two finger scroll and changes to enlarge/+/- but always comes back. It also occasionally pops to magnify and sometimes gestures won't bring it back. Only restarting Safari brings it back.
I also had a problem where the curser would jump around and "hover" select but that was because Bluetooth was enabled. Still does it but only occasionally.
I say keyboard because the " “E”, “R”, “T”, “Y”, “U”, “I”, & “O” " keys are electrically connected.
You'd expect a browser issue to affect all keys.
Wait just reread this part:
"I started back up in TextEdit the letters weren’t working once again. "
So it does happen in TextEdit but only after you've used Safari?
