Default Averege MPG RESETS

When my car is off for at least 8 hours the average mpg resets to 0 can anyone tell me what the problem is. Car is a 2000 convert.

Battery voltage dropping too low when cranking. If you have HUD, you'll notice the page resets to oil pressure also. New battery is in your future, unless the connections are loose or corroded allowing the drop. I think it's 8.5 volts it can't drop below to hold the memories, but I can't say for sure.

I agree too...battery dropping below the 12.5vdc min. Either battery is done or bad battery connections.
