“I was driving my truck up a 6% percent grade when the change fuel filter soon warning popped up, about a minute later the vehicle started to lose power, I kept driving to try and get over the hill so I could make it to a repair shop to have it checked out. I was only able to make it about 2 miles after the warning showed up before the vehicle completely shut down and would not restart. …”
