I lost all power going about 45 mph Last night after I let off the gas to make a slight right curve and when I pressed the gas again. My gauges reset and there was a message on the cluster screen that said “SHIFT TO NEUTRAL AND PRESS START AGAIN” (it may or may not have said “AGAIN”). I pulled over and while still in Drive with the brake pressed, I shifted to Neutral, and pushed Start/Stop and the entire vehicle reset. The ignition clicked nonstop for awhile but the engine did not turn over. While waiting for AAA, I disconnected my Pulsar LT and tried to start it, but got the same nonstop clicking. I scanned it and got a code reading: “P16A7: Engine Controls Ignition Relay Feedback Circuit 2”. ANY and ALL feedback is welcomed. 2019 (late/new model) GMC Sierra SLT 5.3L Crew Cab Short Bed ~115k mi if that matters. -

Coming home from a four-hour trip Sunday towing a small utility trailer, my truck dropped to idle while at speed on the interstate just a few miles from home. I was lucky and able to pull over to an exit ramp with zero power. While coasting the display popped up saying reduced power for a couple of seconds and the engine light came on. While still on the exit, all power restored, message went away, and I was able to make it home on back roads. While it was still running I pulled three codes: P0087, P129F and P228B. Cut it off, unloaded everything and then went to move the trailer. It turned over for a few seconds then busted off (longer than normal). As soon as I put it in gear it shut off. Got it to the dealership and awaiting the results. Truck only has 1,404 miles on it and was delivered from Flint a few weeks ago. All displays read fine, fuel filter, DEF fluid, etc. Engine light still on. Just FYI to add to the list of L5P problems
