Check your wiring from coil to the ICM...and yes, also ensure ICM isn't fried

hey guys I have a 1993 Silverado 5.7 350 throttle body injected automatic truck. the problem is that it dies while your driving it down the road completely random it seems. when it dies there is no rough running process before or after and it starts right back up after turning the key off then back on. I have replaced : coil, plugs and wires, complete distributor, timing chain, intake manifold gaskets, EGR ,vacuum hoses everywhere , fuel pump ,fuel tank ,fuel filter. I have also installed a rebuild kit on the throttle body and rebuilt the injectors as well. I have had this truck for some time and am a heavy equipment mechanic by trade. I was told by a friend that it may be clogged exhaust because it smells like its running rich and has no check engine light its pretty random when it does die. any help would greatly be appreciated and I will answer any other questions you have as fast as I can thanks!

Hi i have a 1994 5.7 tbi vortec and I had the same problem with mine ànd come to find out it was the temperature switch on the intake and that fixed it

Shoot I'm not alone ! Now this is a bigger problem it's frustrating . I got a 93 Silverado, truck ran great no problems. Just put $100.00 worth of gas in the tank drive off all the sudden jerks and stalls . So I thought maybe a vacume line , nope , try to read cods nothing , new cap and rotor , spark plugs and wires , fuel pump , coil , seem to fix the problem tell yesterday my truck just shuts off not the dash light or ac just the motor . Thought about muffler I just recently installed , thinking it's to much back pressure . This is the only thing I changed on my truck prior to these problems . I'm running a 10 worries flow master single in and out with headers and no cat . Now the sound of that right now dost sound right ? What u think ? And I dont know if I'm using this sight right .

COMPLETELY FIXED : after installing a new Ignition control module the truck stopped dying randomly ,but then developed a rough idle. I then warrantied the entire distributor which had a lifetime and was pretty new anyhow. that completely .fixed the truck. runs like a brand new one now super smooth.

So a new distributor ..new cap and rotor and icm is not exactly new distributor ..
