The fuel gauge began flashing off and on for no apparent reason. Does this indicate need for a filter replacement or something else? Is it temperature related? It has been very cold but warmed up today. The flashing issue just started after dark when it was restarted after being off for 2 hours.
Check the fuel level sensor.
All you shade tree mechanics - this is clearly beyond your abilities. I took my '06 prius to my local dealer, et VOILA! A couple hundred bucks later, and a car wash and my problem was solved.

Find the temperature sensor(usually around the thermostat housing)'disconnect connector and ground it with a test light. Observe the inside gauge. It should slowly go up. If so, change sensor. Do the same for the fuel gauge located on the fuel tank. If gauge move to fill as you groung the sending unit wire, change sending unit. Test the right wire. Ask for further assistance.

Check online in other forums of this particular issue. Others may have had the same issue and have found answers through other sites online. Sound like a bad sending unit "fuel gauge sensor". Unfortunatly, it may be a requirement to remove the fuel tank to gain access to this fuel sensor. If you dont have the means to repair this problem you can always keep track by the mileage that you put on your vehicles tripometer. I know thats a pain but it wont cost you any money until you choose to have the repair done.Estimate your mpg's and the size of your fuel tank by the gallons, and multiply the two. Be sure to keep track and have enough fuel not to run out! Its always better to keep half a tank than an eighth of a tank!

Some cars have a second fuse box under the hood near the battery. See if your car doesn't have one of those.

Maybe it's not running lean. Maybe it's misfiring. Since you put in new fuel parts and that didn't help, maybe there is an ignition component that fails when it gets hot. A bad coil can do this, also the igniter-rarely, admittedly, but you could have it tested. When it stalls and won't start, if you check for spark and find none, it would confirm an ignition problem.
I hope you find it. Post back and let us know.
