Your digital dashboard display went completely black when you tried to start your car, leaving you unable to see your gas level and other important information. The infotainment screen and heads-up display continued working, so you could still see your speed. After turning the car off and restarting it about 15 minutes later, the dashboard display returned to normal and has worked fine since. The issue may involve a loose electrical connection, software glitch, or a failing dashboard display unit that may need inspection or replacement.
