-11 random code

Hey while only under a load my car is flashing code -11 and it quits. You let off the pedal and then get back into it and the car go’s again. Any ideas on what could be causing it.

The list of error codes shows that -11 is a stuck pedal. I can assure you the pedal is not stuck or nothing is getting in the way of it operating normal.
If anyone has any info thanks
