Are you getting any codes? This is an uncommon problem and probably has to do with the engine management system. I would test drive it with a scan tool attached to see what the sensors are reading at the time of the malfunction. It could be as simple as a bad sensor (MAF/MAP), a vacuum leak, or as severe as a faulty torque converter.
