On ever fill up, I log how many hours are on my pickup. On the last fillup, I was at 8.2 hours with 20,148 miles. That means I've travelling at about mach 4. On the tank before, it was 19837 miles with 645.5 hours. What would cause me to lose all my hours???

Did you turn on the flux capacitor? It warps the time space thing.

Seriously I thought I had low miles for the amount time on clock when I first got mine. I thought it was part of the permanent memory (can't be reset)

I see in your sig "Knowledge is power" if the reverse is true, that means our trucks are some smart machines.

Your cluster is bad. Same thing happened to mine. It reset to 0.0 hours and started over. They had to replace it (I lost a few miles on the replacement, too. :D).

So did yours reset only the hours or miles as well? Did it do it more than once?

This was the beginning of the end for my 2006 -- during a panic stop the antilock brake controller failed to operate and I spun the truck nearly clear around when all 4 wheels locked up. The engine died and it took a long time to restart. The hour meter reset (repeatedly), the ECM lost all calibrations, BCM would randomly reset all of the preferences, mpg down 25%, courtesy lights wouldn't go out, auto A/C would blow heat then cold then the fan would come on high for awhile, then it wouldn't work at all, on and on. Three instrument panels were replaced, along with the ECM, BCM, Door modules, new ground wires installed, new batteries, ignition switch, wiring, Auto A/C controller and sensors. Truck was at the dealer for over 6 weeks. GM finally admitted it is a problem with 06's, opened a TAC file, theorized that a voltage spike pulverized the electrical system, and put me in touch with the district service manager, who said he would do nothing more because TAC can't recommend anything else to do. He suggested I pick the truck up and "make do..." Still has random episodes of clouds of smoke under moderate acceleration, sometimes there is no throttle response at all for a few seconds (nice merging into traffic!), and the transmission occasionally shifts into T/H mode and up and down shifts erratically several times for no reason and then straightens itself out.

Dealer had a scan recorder hooked up on the truck for weeks, but could never get any codes on it. Seems that although some sensor / wiring / control / wire is malfunctioning, it never sets a code, so the dealer is clueless about what to fix.

Filed for arbitration from the BBB, and GM is reviewing my request for buy back. Too bad, the truck ran great for 14 months and 14K miles before all this.
