[05Path]

My 05' Pathfinder runs great but out of nowhere while driving all electrical (fan motor, all dash lights and gauges) shut down but the engine is still running however there's no acceleration. It lasts for a few seconds and everything comes back on. I have spent over $1000 replacing parts as suggested from mechanic but nothing fixed it. Anyone else have a similar issue? Engine light was on for catalytic convert. I replaced them and O2 sensors. Nothing changed.
