Weird stall issue?

[ganma_ca]

So not quite sure what's going on here other then it may be fuel/electric related. I was leaving work today everything was fine, I get to a stop sign and the ca just dies????? I was like wtf??? Start it back up and keep on driving. Well about 2 lights later when I get into 3rd/4th ca starts sputtering/losing power, but not dead. Then starts seeming like it's mis-firing. Then again like wtf? After getting it home, idles just fine, not sure what in the world is going on. Anyone have any idears???

Ok will do I know right now I am running a range colder then normal and some NGK's bcpr6 or 7 I can't remember but you think the are fouled? (I know I am running rich because of the KA24E maf, so not sure if that makes a diff.
But yeah will do tomorrow! Thanks Float

Ok So now I pulled the plugs.... White tips and..... Brown/black porcelin???????? WTF!??!?!?
I changed these plugs like a little over 1 year ago but I have never seen porcelin turn brown/black what is happening?????? It sure ain't from rust either looks burnt?

Ok well I guess that's supposedly normal a greyish white but not too white tip and the porcelin browning a little?
