Update. i took to dealership and somehow along the Driver side of truck just past the gas tank, and by frame Rail there was some wires freid where they went into a plug. They repaired and replaced a fuse. Seems to be fine now. thanks for the responses
Was driving home from vacation 10 hr drive each way. Truck drove fine and still drives fine, but check engine light come on in why drive back home. I had diagnosed at Autozone and it showed maf sensor. I driver 6 hour home and seemed fine except for light on. I changed maf sensor but still light on. Any ideal what it might be or what to do?
