Vehicle stalls while in motion. Figured out it may be running out of gas due to the gauge not working. Now, it stalls when it only has a half a tank of gas, not completely empty. Put 16 gallons of gas in the 30 gallon tank, truck runs smooth. Replaced the fuel filter twice. Replaced the battery, tested the alternator, results no alt. Problem. Check engine light on, speedometer is off, gas gauge is off, and the rear view mirror display lights go on and off erratically. Biggest problem is when I break the truck will shut off. This has been going on since Nov. 2010, when we replaced the battery and quit using a certain type of gas it seemed to be fine. Now, it is acting up and today was the first incident since early December.
