The revs jump up because when the clutch is pulled in the engine gets disconnected from the wheels. This means that it no longer has to move the weight of the car and it's driver so the engine gets more gas and floods

Technically, it never touches the flywheel - the clutch disc does. You can stop the flywheel (stall-out the engine) by engaging the clutch in gear with the brakes firmly applied.
If the vehicle has an automatic transmission, then the torque converter clutch is probably sticking. The clutch is controlled by a solenoid, that moves it back and fourth. The clutch material can get stuck to the inside of the converter and stall the engine. Have the transmission flushed, and if the problem persists, then have the solenoid replaced.
rapid release of the cluth pedal. When stationary can cause a car to stall. When on the move can restart an engine, as in bump starting.
It is when the clutch will not hold. Like you can be driving up a hill and you can rev the engine with no increase in road speed. With the park brake set hard, the car should stall if you attempt to drive off. If you have the clutch out in first gear and the engine can still run and the car isn't moving, the clutch is slipping.
An engine may stall when put in gear due to several factors, including insufficient fuel supply, a faulty ignition system, or a malfunctioning clutch. If the fuel pump is not delivering enough fuel or if the air-fuel mixture is incorrect, the engine can lose power when a load is applied. Additionally, issues with the clutch, such as it not fully engaging or disengaging, can cause the engine to stall. Other potential causes include sensor failures or problems with the transmission.
It would stall out at lights because when you need to shift you have to let up on the clutch easy when your changing gears; therefore you will stall out if you let the clutch go too fast.
There are three common problems which are causing your car to stall when the clutch is engaged. These problems are either a worn out clutch plate, a warped pressure plate or disc, or a damaged throw out bearing.
A car can stall with the clutch engaged while slowing down due to insufficient engine power or a lack of fuel reaching the engine. If the engine RPM drops too low, it may not maintain enough power to keep running, especially if the driver is not applying the throttle. Additionally, issues like a dirty fuel filter, malfunctioning idle air control valve, or a weak battery can contribute to stalling even with the clutch pressed.
A car may stall when the clutch is pressed in if the engine is not receiving enough fuel or air, leading to a drop in RPM. This can occur due to issues such as a faulty idle air control valve, a dirty throttle body, or problems with the fuel system. Additionally, if the clutch is worn or not disengaging properly, it may create excessive load on the engine. It's essential to diagnose the specific cause to prevent stalling.
Someone has to pick up the rear end and run with it, starting your engine when he drops it. (and if you spin out and stall you lose the race )
