Hello, I have a new to me 2015 Rubicon JKU. It has several mods but the issue I am having seems to be electrical/motor related. The Jeep randomly will buck (like I hit a pothole) then the RPM drop to ZERO as it shuts down. All other electronics stay on, radio-lights-etc... The Jeep then just restarts on it's own. It's kinda like it has a brainfart on how to run... I haven't had to pull over or crank it to restart, it just does it on it's own after a second or two. Has anyone else had this specific problem?
