2004 Toyoya Avalon Sometimes will not start.

Please Help!! My Wife's 04 Avalon has an intermittent no start. When the key is inserted into the ignition and turned on the car does not crank. Also when you turn the key to the start position the screen in the center of the dash with the time and check engine lights and odometer goes black. I can hear the fuel pump working and bot the starter and ignition relays click. I am stumped. After sitting for a bit maybe 10 minutes or more the car usually start no problem. The car just went 25 days without issue and now its doing it every other day! Any suggestions or ideas? I was thinking maybe the ignition switch.
