Ok so i would be driving listening to music on the freeway (i would be in about 4th gear or so) then suddenly out the blue my RPM meter drops down to 1000 rpm and my car would shut off for a split second also my “AT CHECK” light would flash and then go away. And if it is night time my headlights would flicker on and off until it’s back driving normally. I believed i uploaded an attachment on what it would do. Look at the RPMs when watching the video.

 

Get your battery load tested and pull any codes. Make sure the battery terminals are snug. Gl.
