2004 ram 4.7L reg cab 4x4. Briefly loses power when I blip the throttle. Not always. Doesn't seem temp related but hasn't lost power at speed (only at idle rpm when I start to throttle back up). Did die yesterday when pulling into driveway. See video and notice dash lights flicker and radio goes off. Ive checked grounds and all are tight and appear fine. No clue where else to look. Ideas?
