2001 Nissan Xterra SE, automatic 4WD. when i drive for extended period of time, the tach, odo, and temp gauges go out. also the digital mile gauge goes out and doesn't record miles. shortly followed by a lurching and loss of power whenever i try to accelerate. its pretty dangerous on the freeway. almost got smashed by a semi this morning. on the online forums ive been searching, the problem is common but no solution yet.... i'm looking into a bad ground. sounds like it could also be the cluster behind the stereo, or bad circuit board. it cant be the alternator because the stereo and lights still work during the problem. only the dash and acceleration are affected. i also put a new battery in but the problem continues. any help would be awesome!
