You may have some bare wires that are shorting out on the clutch pedal. Get under the dash and check it out.

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.
you got to give it gas so you can take of and then it wont stall
Cars fequently stall, especially if they are a clutch. If your car is not a clutch, iIwould have a mechanic look at it. It could be a spark plug issue, and you don't want to mess around with that.
It needs a tune-up.
When you stop, you may be letting the clutch out to early.
No. You will stall(or cut-out). This means that the car shuts down and then you have to clutch in and put it into neutral. Then(still on the clutch) turn on the car again.
Is your clutch bad or wearing out ?
A problem in the fuel line could cause it to stall. On a stick shift, letting off the clutch too soon would cause the vehicle to stall.
If your car runs fine cruising, then coming to a stop (perhaps at an off-ramp) you press the clutch, let off the gas, and the car stalls, then most likely, you have a vacuum leak from your intake manifold or low fuel pressure. This is dependent on the vehicle, of course. More information would have been more helpful in answering the question.
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.
