Car dying at low speeds and stop lights

[Kylocheff]

I have a 2014 R spec 5.0, it sometimes dies when I’m stopped or coming to a stop and it loses all power including electrical power for maybe 10 seconds, then the dash lights come on and I can start it again. I just replaced the crankshaft sensor and that didn’t fix it. I’m assuming something electrical.

I would check the battery cable connections (I think the battery is in the trunk, under the floor). If the cable clamps are loose, those can make strange things happen.

I had the exact same issues with my 2012 R Spec. Turns out the ground is terrible on these cars. Disconnect the ground terminal from the battery in the trunk and clean both the post and terminal. Also disconnect the ground to chassis. Should be two screws, 12mm I think. If you notice the only metal to metal contact are the two screws. What I did was removed the paint where the connection touches the car so this gave it more surface area to create a better ground. These seems to have resolved the issue. There are also two more grounds up front on the engine. I would clean those connections as well.
