Engine dies at speed, and will restart in a second or two (manual transmission). Gages go haywire. Can sometimes reset condition for a while (minutes to an hour) by turning key off-on, or restarting while at speed - sometime not. Has gotten much worse, car now has 185,000 miles. Replaced engine pcm - no effect. Replaced engine tipm - no effect. Kind of scary when this happens pulling out into traffic. Software design defect?.
