2013 GMC Sierra with 265,000 miles, vehicle started running rough as if it was running out of fuel, all dash lights came on.
Vehicle ran rough and dash lights came on but still ran. Drove a bit further and lights went off and vehicle ran better but still not running normal. Drove home and parked and when I went out the next day to start it would not start, turns overall ok and attempting to start but will not.
