So I took to my 17 RM for a little ride Sunday. Middle thirties but sunny, it got up to about 40 degrees. On the way up to visit the grand kids I got her up to a around 110 mph a couple of times. No traffic on freeway. At around 100 it seemed to hesitate then smooth out. On the way home, riding about 70 mph it stalls. I started right up with out stopping, a little ways down the road she sputters, doesn't stall. Then I loose my acceleration. I could get it up to 45 mph. Now, there is major road work so there is no where to pull over so I stay to the right, put the flashers on, and continue for quite a while till I hit an exit. I notice as I pull off it isn't loosing any more power and if I shift up to 4 it will hold at 45 mph. It was cold, it was a long day, so I decide to ride home on the road, about an hour, at 45 mph. I get home. Shut her down. Let it sit for about 10 min., and started it up. She seem to run good, but I am a little scared. I did have her die on me last year because of throttle body failure which seem to act similar to this. The power command stated it was a ECU Failure or fault. Anyone have a similar indecent happen to them?
