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.

Sweet it worked. At first glance I didn't notice anything but looking at the second pic the large gray resistors and powdery blues to the left caught my attention. Maybe they're supposed to be that way but the only resistors I've ever seen are striped for the resistance values, and typically glossy. Someone who knows what they're looking at please feel free to chime in. Thanks to all of you guys thus far
