Large white smoke at start up then lurching on the freeway.

2017 BMW 440i grand coupe 91000 So long story short when I started the car white smoke for 2 seconds (figured it was condensation) then 25 minutes later on the freeway lose of power with lurching(like the clutch was slipping). Pull over. Engine was not over heated. No warning lights on dash. Hx of coolant leaks.

Service History: Coolant system replaced 70000 miles Sparks plugs replaced/injectors replaced 85000 miles Oil filter housings w/o cooler 83000 miles

Fuel injectors? Transmission? Any ideas please
