Thought I had this issue fixed after I replaced the igniter and dizzy last year to fix a code 12. Apparently not. This has happened twice now. Once before replacement parts, and this is the first time since new parts were installed. Left work yesterday and only got about 5 miles and the car sputtered a little and then just knocked off while I was sitting at a stop light. Had it towed home 35 miles and was able to crank it back up and drive it off the rollback.. Temp never got hot, has been staying just under midpoint of temp gauge (is that normal op temp btw?) CEL didn't come on this time either like it had before. It's a '94 GT 5sp. Not sure where to start. I've read it could be coolant temp sensor giving false reading to PCM and killing the engine bc of high engine temp. Does the 5s really have this fail safe?! Thought it was odd. Also read it could be clogged cat converter, but not throwing any codes. Considering I've replaced just about all the ignition components since owning the car I believe it may be fuel related. Any input is appreciated. Thanks in advance guys.

hmmm, I don't think there's anything wrong with those particular resisters. I don't remember why but I think those are normal, just some special type. be sure and check both sides of the board and look for things like a capacitor with goop coming out of it or burn marks, and melted pieces.
the thing I'm wondering about is the way some of those computer chips look like part of it is shiny black and the other part of it is dull gray like the protective coating has melted away or something. several of mine looked even worse. and I would use a flash light to look carefully at the 6 cylinder shaped black and silver capacitors, especially the big one in the middle-left. Often you can see physical defects but, even if you can not that doesn't prove the electronics work as they should. especially if it runs most of the time and only acts up once in a while.
