The car also likes to almost stall when I pull into my driveway and when I reverse then. My cluster lights are really dim as well as my climate control lights. When I test drove the car it had none of these issues. But I Bought my car with this issue. I have removed the aftermarket alarm that ties into my ignition switch. Replaced 02 sensor. Still same stuff. It will shut off on the freeway randomly but bump start itself back on. :/ I need help this is starting to become frustrating.

 

Battery is relocated to the trunk too.
