HELP!!!!

Hi Guys,

I own a 2006 hyundai tucson for 7 months now and since this past week have been experiencing that when jeep warms up and engine is hot it sometimes stalls/cuts off for no reason at all. Brought it in to dealer and was told nothing wrong as no error shown up when checked with computer. When picked back up same still happened again and Fuel Pump changed and was told that was the fault why it was happening now its still occuring and was told they need to order new computer and that should fix problem for sure.... Anyone with any advise or similar problem that can help shed some light on what is really cause of this?


Thanks,
