Please help, 2001 excursion v10 sudden power loss

My excursion suddenly lost power after sitting in a long traffic jam. I have a scan guage II set up and didn't see any signs of over heating however when I went to accelerate back up to highway speed my motor revved up to 3000 rpm and just lost power I ended creeping on the side of the road at about 15 mph and barely maintaining that. The motor was not willing to revv up. I reached a spot to pull over and shut it down for about 15 minutes and started back up and drove off with no noticable issues. I have 211,000 miles on this motor and I am going to change my coil packs, I think they have been there since the truck was sold new....I changed four of them to address a miss and have six left, I will also be changing my fuel filter. We are about to pull our camper accross country....about 1400 miles if anyone has had a similar experience I would appreciate any advice you can give me.

sounds like it is in limp mode, un hook battery and let set for 10 min then hook back up, this will reset computer. a bad thermostat will make truck act funny and give a flase reading then it will go into limp mode

Forgive my ignorance here......the thermostat you're refering to.....is that the thermostat on the top of the motor that is rated at 195? I also had some spitting and sputtering while it was limping along the side of the road.....Thank you much for your reply.

It could be a wiring short as well caused by chafed wire or rubbed wire. Have a code read, find out which is the problem, locate that device then trace its wiring back to the computer module and exam the wiring.

with that many miles, I would check the cat as well. some folks pressure test it, others use a heat gun to determine if the heat pattern is correct.
