CEL Light on!
Just my friggin luck I get a CEL light at 39965 on my 06. I did notice something strange and wonder if this triggered it. I filled my tank up that morning drove to a store. As we were leaving and were at the on ramp to the 60E in CA I noticed my DIC stating fuel low and the gauge was below E. I knew this was bs because I just placed 26 gallons in it. I pulled over shut the truck off and then restarted it. The gauge was reading normal at that point. Got half way home and bang it was reading below E and Low Fuel. Pulled over shut it off and restarted it. It's been fine since but now I got a CEL light. Performance is the same at this point, could the issue above withe guage/sending unit trigger a code for a CEL to come on?

i see you have a 06. ill bet your light is on with p0460 code. seen several of these issues and there is a reprogram out for this code. it repairs false fuel level input to the pcm due to irratic readings from the sending unit.
