Could be a vacuum leak in the servo, if it has one, causing a weak mixture
and the stall. However a loose connection in the igntion circuit would
cause the tach (if electric) to drop to zero instanly and cut the engine.
Both of these faults will cause the engine to die when not in gear (or in
gear with the clutch depressed) but possibly not when it is in gear with
clutch pedal up.
