Question about 1993 GMC Sierra K1500
Thank you for your input. The truck does not seem to have a pattern such as hitting a bump or driving on rough roads. Once it has shut off while on the expressway with very smooth road while in cruise. Weather does not seem to matter either. I have minimual keys on my key ring and I also suspected the ignition or wiring in the steering column. While driving I have wiggled the ignition switch, banged on the column, and place the tilt steering in many different positions. I have also pulled all fuses and relays - checked for corrision and replaced. Still cannot duplicate this issue, but it still shows up unexpectedly. I would appreciate any other thoughts or ideas.
I am currently having the same problem. While driving to work the other day, my lights dimmed, my CD player shut off, and the battery gauge dropped significantly. It did this for about 5 seconds, then out of nowhere, the lights brightened, and my CD came back on, and the battery gauge was on the rise. I've had my battery, alternator, starter, and much more tested and checked. I just put a new battery in it. The truck doesn't shut off or anything, yet; however, the battery gauge dropps every once and a while. I think our problem is the ignition switch. One of the wires could be shot and needs replacing. A lot of times that is why cars do what is happening to ours.

Ihad a 1994 GMC K1500 with a 350, and it was doing the same , lots of time it had to do with the module , in my case the probleme went away after replacing the module. try it

I believe that you said originally that your dash also goes"dead" like does the voltmeter drop and all the guages?
If so I would suspect a main wire that feeds the ignition Switch.
But having said that I wish I knew if you were loosing spark or fuel Have you gone to rhe fuel tank and wiggled the harness there? Would you call me So I might talk to you about this in the mean time Ill look in my database and see if I find any old repairs that might relate
