Saleen Odometer Flashing Out

Noticed this problem while driving. Did not hit any bumps. The odometer flashed out. All other lights work correctly including head lights. Shut car down start back up 3 mins later and it flash's on as advertised. Because it comes back on I am sure its not a fuse. Any ideas? Or has anyone had this happen?

No work to the dash. Found out it is probly the sodder on the cluster itself. And it only flashes out when its really hot outside.
