What is your question?
Problem started when lightning struck adapter plug going to inside truck where a de-humidifier was running. Have had 2 Highly qualified shops agree that truck should sell for $500 on Craigs list but I refuse to give up on my well cared for Truck. If what "Pushrod" said is true, I'll change the Ignition Switch ASAP! Did the last Guy who asked this Question ever feed-back that this fixed Issue? The Truck runs great but after a while it starts losing acceleration and then it starts Shaking so bad I'm afraid it will blow out my Engine Mounts! Please if you have any idea what I could do I would be very grateful. I've been trying for over a year to fix my Truck. Thanks for any Clues you may have to remedy these problems!!
