Power loss after warms up

The injectors get 12 volts of battery power, and the engine computer switches on /off the ground for each one to make them squirt. Not as likely. Another thing you can do is let the truck idle tonight, and look under the hood in total darkness, may see tiny sparks along plug wires and associated parts. Plug wires are not easy to do, but there are write ups on here you can search out for swapping them without having to take off the top of the engine, takes time.

I just replaced the wires - good news/bad news.
Good news: It was easy!! I was worried after all the write-ups, but I was able to worm my hand behind the intake & do the job quite easily....without taking any parts off the engine. Took me just under an hour.
Enough gloating....on to the:
Bad news: The problem still exists. It ran great for 15 minutes or so (better than before). After that the problem returned.
I got it tested at AutoZone & following are the codes they gave me:
- 300 (Random cylinder misfire detected)
- 301 (Cylinder 1 misfire detected)
- 306 (Cylinder 6 misfire detected)
- 1690 (Neutral position switch circuit high input)
I also read that this could be a symptom of the CAT's going out - The post I read said to look under the truck to see if it is glowing red - Mine was not.
Any assistance is appreciated.
