Any update yet? I just converted my SLT to a sport and am running some TRS Can-Bus HIDs that worked great in my 2011 but are having this exact issue as you in my 2015... Both headlights turn off and back on twice after 20 mins of driving, then at the 25 min mark the go completely dead...Except i have to shut the truck off and wait 30+ mins before they will come back on usually..sometimes they come back on right away after shutting it off though but not usually.
I plugged the ballast in to the low beam plug and crammed everything inside the housing, and i too am not running a relay harness...i've done a plug and play installation. I've heard it may need a capacitor from a local company?
Edit...(additional information) fog lights and driving lights remain on. low beam is the only one that goes out for sure, have not tried high beam when the lights are out yet.
