The way you describe it, it's most likely in the ignition... If it only happens once, then it could be a loose contact somewhere -- hall sender? coil? ECU? It could even be a bad contact in the ignition switch itself -- I've had that happen to me, and the exhaust would bang so loud, people were diving for cover :-) Try wriggling all the connectors while the car is idling.
