Have a 2000 International with a DT466e. Having some problems that seem electrical. Will shut off at random intervals, sometimes it will start right back up, sometimes not. Some times it just momentarily cuts off then powers back. When it does die, it's like the computer in losing power, no lights on the dash or buzzer. The inductor for the auto transmission never seems to loose power. The dash has been off and on for a a while now, just thought it was the dash, but guess I have some bigger problems. Some times when trying to restart the beeper and engine warn light will kind of flicker and it wont restart, but if they are on solid like normal it will fire back up. Checked every connection I could think of everything seems good, something is loose that I can't find or the computer is going bad. Have it ion the shop but of course it runs fine now. Anybody have a suggestion where to start?

A common recommendation is to check for good grounds. Some trucks may have several grounding spots from cab to frame,
and it is worth some time to loosen, clean up and check all of them.
I had some issues like that a few months ago, and I cured it with this tip.

There are two relays on the firewall that get some corrosion on the pins. It should be a red 10 ga wire the one that causes it to cut out. You can turn on the key and wiggle the wires and it should beep if it's losing contact

Had one that acted a lot like that, same motor and same truck, ended up being cam sensor. I wouldn't have thought a sensor like that would go in an out but thats what fixed it. If you have another truck with same series motor you can swap the sensors to check. The dash problem with the gauges going in an out is just a common problem those trucks have and is most likely unrelated. And like previous poster said its a good idea to check and clean all grounds to batteries and frame you can find.

Trace the wire coming from the fuses in the battery box both hot and ground, they are notorious for rubbing through mostly near where the trans and engine meet. Usually there is a connector there also, it can be eliminated splice and shrink tube. Those wires are direct power to the ECM, the flickering is a sure sign there is a swollen green spot in your wires. Be sure to be sitting down if you want to replace the dash cluster, also a common problem I've seen it in school buses hundreds of times! The only truck that takes more abuse than a bus is a garbage truck!

I had a 97 international that did this. I fought it for a good 3 or 4 months. Check for loose connections on the back of the key switch. This can be a problem at times. Where I found my problem was an odd looking $10 relay up by the engine. I appologize its been 4 years since I fixed it and cannot remember exactly where it is. However once it got hot or something it would kill my power to the computer. Once it would cool off a bit i could start it up and go anywhere.
Wish I was still around this truck and I would take some pictures for you.
