Well today I called dealer (4 hours away) and the service guy said to bring it in. I asked if there was a quick fix to clear the flashing light but he said "If things were that easy to fix we wouldn't need service centers would we"? Wasn't happy with his attitude and I agree but I think he could have said it in a different way. I told him I would find a dealer locally as they could probably use the work. This morning I disconnected the negative battery cable for about 10 minutes, then reinstalled it. Still had the flashing light. Started it up and backed it out of garage and flashing went away. Took wife on about a 12 mile tour of the woods and sand and had no more problems. Hope this was just a fluke, but not counting on it. The buckiing and rev limiting above 20 mph I mentioned, was because of being in 4WD.
