So additional info,,,, when driving 50 mph up hill engine bogged and almost died as it felt like brakes were being applied I almost made it off the road ... was idling on the side of road at a stop.
Realized reverse still worked and was able to back off the hwy. to a safe area.
So I'm thinking that the transmission told the engine not to go forward while traveling up the road, but reverse works fine.
Was on some 60 miles rough dirt roads in Glacier NP . Maybe ground or wire connections are to fault ??
Drove 1800 miles last 75 days with no issues
