I am stuck here in Metropolis IL. Just north of Paduca KY. here are the symptoms of my truck.

1) Bought fuel is MO and when I started the truck the SES light came on and I lost bunches of power. I pulled over stopped for a few to look under the hood and started it back up and all was fine. I drove for another 300 miles stopped for gas again all was fine. I drove for another 20 miles and the ses light came on and she shut down on power again. I can start the truck and it runs and sounds fine I can drive it around for about 5-10 minutes and beat on it and it takes it OK. Sometimes I get 3 miles sometimes I get 10 feet and the SES light comes on. I have read about a harness issue on here and I have read about bad injectors. The truck is at the dealer right now and they are going to start work in the AM. I need to be in FL ASAP for a race can anyone on here point me towards an idea that might help the dealer??

Can be a lot of things shuttin her down, fuel pressure regulator, maybe got some real bad fuel plugged filter etc etc?

I had similar symptoms when I got a batch of bad fuel. If it is fuel related they should be able to identify it pretty quick. The downside will be the time it takes to drain the tank and flush all the lines. Mine was tied up for most of a day. Good luck and I hope it is something simple.

I changed the fuel filter and it did not get any better. I noticed that the fuel pressure was down at the fuel prime pump.

I'm thinkin' injector harness short.

So what was it?

Wonder if it could have been the Mass Airflow Sensor?

Check for the harness rub.

If the SES was on then the codes would be helpful.

SES light? What was the code? I take it you don't carry a code reader. That would be helpful in this case.
