Car died in traffic.., And it started right back up after havin it towed home.. **FIXED-ECU Options

[kevin311]

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.

Yeah that's what's odd. Originally even with the code 12 the car drove fine. After the salvage replacement it was fine for about a year, so I figured it gave out, def got my $35 out of it. So went new and still had the code. Replaced igniter with new and cleared the code finally. Until a couple months ago it's been intermittent. Last two weeks it's driven great with no CEL. Cranked it up yesterday just to listen to it. It's odd, it runs great until it reaches operating temp and then it stalls out. Did it twice to confirm. Looks like I'll have a chance today to open up the ECU and put a multimeter on the wires for the diz and hopefully get to the bottom of this nagging issue.
