Running like UVCH bad but it's not

Truck ran good for 200miles down the interstate. Stopped to drop off my load and let it idle for about a half hour and it started missing like a harness went bad. Tried the usual, unplug one harness and truck shuts off, unplug the other and only a slight change in the sound. I changed the harness and it made only a slight improvement and it still runs like its not firing on that side. Ohm'd wires from idm plug and they all fall within spec of 2.8+. Took off valve cover and pulled each plug from the injectors while running. Cyl 1,3,5 cause no change in running, cyl 7 makes it run worse. So it seems like 1,3,5 are dead in the water.

I think this points to idm or could three injectors go bad all of the sudden like that? Ill buzz test them when my brother gets here with my scan tool.

Any ideas?

Really icp?

Buzz tested and they all buzzed good. Shows 1,3,5,7 open circuit so I would think that points to wiring still.
