Filled gas tank. When I started the truck back up, the gauge didn't register the gas. Drove eight miles and with my foot on the gas it started to slow down. Pulled over on the shoulder of the expressway. It sputtered when I stopped. I finally got the nerve to cut it off. I cranked it about ten minutes later it went about a thousand feet and did the same thing. This time it sputtered again when I tried to crank it till finally it would never even turn over like the battery was dead. While waiting on the tow truck it did loose compete power within the hour. The flashers would not even work. Laymen terms please as I am a complete girly girl.
