Was driving today and my dash went blank check engine light came on then I stopped and put it in park it clunked into park then I put it into drive to make it to the farm a mile up the road then I got there and put it in park it didn’t clunk turned it off too then I turned it back on the check engine light was off my dash was back to normal and it drove just fine? it’s a 2013 5.0 liter fx4

 

First thing I would do is have the battery tested. Weird things happen when a battery is starting to fail. Make certain the battery cables are secure as well.
