I picked my Model S yesterday and drove about 75 miles home. We are waiting for the electrician to start installing the 240 volt outlet. For now we are using the 110 volt outlet. The car indicated that it was charging at 3 miles per hour. After 2 hours of charging, I got a message from the Tesla app saying "charging has been interrupted". The status on the app said charging stopped and to "check cable power". I went to the car and the charge port was glowing red while the charging cable by the outlet was flashing orange. I tried unplugging the charging cable from the car by pressing the button and waiting for the charge port to turn white, but it stayed red. Later, the car started charging again according to the app and after I checked the car. Is there a reason why the car stopped charging after 2 hours and then started charging again?
