PCM IDM relays clicking truck turns off

Woke up this morning the truck started acting up lights illuminating on the dash and heard a clickg sound. It is coming from the pcm and idm relays. Truck will run for about 4-6 seconds and turn off I was able to bring it to 1800 rpm before it shut down. Got guys waiting on me ready to work and a trailer to haul after the job.
Thank You for the replies.

of COURSE! Iím trying to hide that thereís a problem with the truck as some of my family members simply ENHANCE my truck issues. So after helping out around the house when asked I came back to the truck 15 minutes later and it turned right on. Sitting in the drive way now still running has AIH delete code as usual, I canít remember if cleared the code when I reprogrammed or if that is separate for the p0603 code and PO381 GLOW PLUG INDICATOR CIRCUIT MALFUCTION Code? That is the first time I have seen the glow plug code could that be the start of the trail to fixing this? I feel like itís only a matter of time till it happens again.

Are you running an OBDII gauge (like Torque Pro) when this happens?

No the tuner is usually plugged in I disconnected it earlier with no change in results. The truck has ran well for about 30 minutes today with it plugged in thatís how Iím able to read the codes.

here are 2 videos of what a going on the engine turned off on its own. So much time had passed I was about to revisit this thread the other day now and report my findings yeah the problem is still ongoing . I just got one of my test wires put it to the PCM and grounding PCM as I just found out my PCM ground clamp is not there yet there was no difference . Has anyone had this situation occur before ?

Sounds and looks like you got some loose battery connectors, dirty engine ground connections. Is your truck an 02-03?

The block grounds do tend to corrode check them out too.

The truck appears to be cured after installing the PCM ground clip I made my own. Do you know where the engine grounds are? I am interested in checking those to confirm they are looking good as well.

The ďclipĒ is just a flat piece on metal

Engine grounds are on the front of the block not far from the batteries. Just follow the ground wire to the bolt/nut. They can be rusted and hard to remove down there depending on where the truck has lived.
