I noticed that a long time ago,but never asked.
Why in some earlier planes (CR.42,G.50,MC.200,Gladiator,Hurricane Mk I),when you pull its nose down,the engine looses torque,and if you keep diving,it stops?

Carburetor engine. It becomes starved for fuel when pulling a negative g.

carburator.
when you have negative G the fuel dont reach the engine
newer plane are with injection

Carburettor versus fuel injection
Early in its development, the Merlin engine's lack of direct fuel injection meant that both Spitfires and Hurricanes, unlike the Bf 109E, were unable to simply nose down into a steep dive. This meant a Luftwaffe fighter could simply "bunt" into a high-power dive to escape an attack, leaving the Spitfire behind, as its fuel was forced by negative g out of the carburettor. RAF fighter pilots soon learnt to "half-roll" their aircraft before diving to pursue their opponents
