If your "low speed" needle wasn't set correctly it can die during rapid throttle changes. It might run OK when you slowly feed throttle in and out. But when you advance the throttle quickly (such as on take off) it can die.

Next time, before you fly, warm the engine up a bit. Then with the plane restrained let it idle for about 30 seconds. After idling for 30 seconds whack the throttle fully open. It should transition smoothly. If it doesn't, the low-speed needle needs adjustment.
