When the plane flies nose up, the wing's vertical component of lift is reduced and ability to gain or maintain speed is diminished because the plane is flying uphill.

In normal flight, a wing creates lift because the pressure below the wing is greater than the pressure above the wing. This difference in pressure effectively "pushes" the plane up, and it is the result of several things, including the contour of the wing, the angle of the wing with respect to the oncoming airflow (angle of attack) and velocity. This airflow in normal flight is typically very controlled and smooth (laminar).
When an aircraft stalls, the angle of attack is so great that this controlled airflow separates from the top of the wing and becomes uncontrolled, or turbulent. This condition greatly changes the pressure distribution on the wing. The lift drops dramatically, and the aircraft will start to fall. Stalls can often be corrected by decreasing the angle of attack and letting the aircraft increase velocity, thereby returning the airflow over the wing to a laminar state.
The X-15 rocket powered plane was quite a high flier. According the sited source, it holds the record for altitude at 107,900 m (354,200 feet). That's about 10 times the altitude of your typical jetliner. Other jet powered high fliers are the SR-71 and U-2.

Not sure how high but a plane stalls because it can no long grasp the air around it to make it fly and it will stall and fall back to the ground. This is usually cause when the nose of the plane is tilted up towards the sky and it is at more than a 45 degree angle.

Lift results from the air flow taking a longer path over the top of the wing (going faster) which drops the pressure on the top surface, causing a net force up. When the "angle of attack" reaches a certain point, turbulence develops on top of the wing, and the difference in pressure is lost.

A stall occurs when the angle of attack exceeds the critical angle for the airfoil, causing a loss in lift. Typically, this occurs when the pilot attempts to fly too slowly or to pull up too steeply.
The current altitude record for a conventional aircraft is 123,534 feet, set by Alexander Fedotov in a MiG-25E in 1977.

Turbulence over the wing. Instead of a laminar flow of air over the wing, causing lift to happen, the air pattern becomes chaotic, or turbulent, and lift ceases to happen. So far as highest altitude, 80 to 90,000 feet with the SR71 Blackbird.
