I have a 2013, manual, that has shut down on the highway three times. After it sits for 20-25 minutes, it starts back up, and runs perfectly fine. I'm thinking it could be the fuel pump relay switch, however I can't figure out where it is located in the fuse box. Can someone please help? Thanks.

The fuel pump relay is deep inside the fuse box, soldered to one of the circuit boards.

What troubleshooting have you done that would lead you to suspect the fuel pump relay?

Thanks, ronjenx, based on it shutting down, occasional not starting, and occasional burn '13 has a plug in relay, and through deduction I found its location. Will see if this fixes problem this weekend, it'll get a bunch of miles.

Where is the relay you found?

K4 in the '13 box

I guess I misunderstood what you were looking for.
I thought you wanted to find the fuel pump relay.

K4 is a removable relay for the fuel pump on the 2012

K4 is the Run/Start relay. It supplies power to the items that need power during run/start. Included in those items is the fuel pump relay inside the TIPM on the circuit board, as pictured above.
