Stall is created by angle of attack; regardless of the kinetic energy your aircraft has, or the airspeed for that matter, if you take the angle of attack past the critical value THE WING WILL STALL.
If an aircraft was on it's projected flightpath (by which I assume you mean level flight, gamma=0) with a 25 degree nose-up attitude, that means a 25 degree angle of attack.
That is perilously close to stall conditions, if not actually well beyond them (depending on type and configuration) for any aircraft in the transport category.
