1999 Dodge Ram Engine running, but lost power while driving

Thanks for the reply. I don't know what could have caused it, but I now think the gas guage is off. I failed to mention originally that the truck had 1/8 tank of gas and the low fuel light came on about 10 miles earlier. I didn't mention it because the truck has been close to "E" in the past and taken a little less than 26 gallons to fill the 26 gallon tank. I also know that when the low fuel light comes on, there are a couple of gallons of fuel left because it takes about 24 gallons to fill it then. I can't explain why it started again 2 hours after it died, but I was near an exit ramp when it originally died. When it finally started again, I drove off the ramp and into a gas station where I filled it. I have driven it about 155 miles since with no problem. But what I did note is that the most recent time I filled the tank was right after the low fuel light came on and the gas guage read 1/8 tank. I drove 12 miles to the next gas station, the guage still read close to 1/8 tank, but it took 25.8 gallons to fill the tank. I then drove the truck another 32 miles before the guage moved at all off of the FULL mark. I know that is new because historically the guage always moved 1/8 tank each day on my trip to and from work which is 30 miles round trip. I feel pretty stupid. I haven't run out of gas since I was a kid, but that was in a carberated car. Does what I originally described as no power but the engine still running sound like what happens in a fuel injected vehicle when you run out of gas? Any ideas what would cause the gas guage to go askew?
