P R N D display turned red and lost power but no error messages

This problem first happened a few years ago and then went away on its own.

This time I was travelling back from the UK to the Netherlands and I was about 3 minutes from a Tesla Supercharger when I lost all power and P N R D display turned red. I was able to coast off the motorway onto the slip road but the motor would no longer respond.

I used road side assistance who looked at the logs but could only suggest I power off and wait atleast 5 minutes and then power back on. I tried that with them waiting for a couple of times with no success.
While waiting for the AA to agree that they couldn't fix it and therefore the car and I could be brought to a Tesla Service Centre I powered off the car. After a futher 5 minutes I tried again and this time it didn't trip to red when I pressed the gas pedal and we could proceed on our journey.

It was atleast an hour an half before the car would finally drive on without the P N R D going straight from white to red.

I am posting this experience to see if anyone has any ideas as to why this happened.
I am out of warranty and as the problem has gone away I can't see Tesla being able to find anything as I have travelled many kilometers since the problem occurred without any more issues.

I tried many Google searches for the problem but found nothing. Any ideas ?

Thanks for the suggestion. And Oops just checked and this should read "P R N D"

No wonder why the search didn't work!

Search also without spaces "PRND"

A simple fix could be a 12V battery but if that doesn't do, it could be drive unit replacement:

Model S becomes unresponsive while driving!

Thanks for all the input.

And last night on the way home the problem reproduced itself and this time power off didn't solve anything. After 2 hours with help from Road Side Assistance the tow truck appeared and took the car to the Tesla Service Centre. They are now diagnosing the problem but initial suggestion is Drive Unit related based on the log they have. Once I know what they fix I will post more.
 
Just for record it was the drive unit and it was fixed under warranty so thankfully nothing to pay. The service centre explained that as I only have one drive unit (2013 P85 signature edition) it will shut down if it detects a problem to protect the batteries etc. They also said that they had run diagnostics before replacing the drive unit and not found any other problems. Just glad this happened once we were back in the Netherlands and not while we were away in the UK.

Scary experience that I just had. 2015 85 here. My PRND turns red but no error message. It happened while I was driving on the road with AC on.
service appt is 4 days from now, and i need long distance business travel back home with this car. I will drive without AC and phone charging to reduce the possibility of shut down again. Very annoying.

Thank you for your post and update. I was presenting this issue to the Tesla service and telephone call center and they said no codes no issues. But I took a picture today, when it happened again today, multiple times.
