What you need to do is when it stalls out then check to see if your loosing fuel or spark.Check for spark at the spark plugs.don`t just check one.Check all the front 3 a least.If no spark then you probably have a bad ignition module.It is under the coils.Good luck.

Check the Throttle Position Sensor and Egr vavle. Look closely at all vaccume lines and check for cracks, breakage and colasping lines.
