Generally, a change in altitude within a gravitational field is said to increase or decrease PE. I posit that the change in PE never occurs UNTIL there is a change in KE. Thus, in the case of an object with a constant velocity UP, there is no gain in PE until the instant that the thrust no longer balances the force of gravity.
At this point, assuming the thrust fell below the force of gravity, velocity and its corresponding KE would begin to diminish with a corresponding increase in PE.
