could be alot of different problem. best thing is to have it place on an obd2 testor and see if any codes come up. most parts stores will do it for you. they want to sell you parts to fix it. They what can cause it to happen are: bad crank sensor, bad idle sensor, computer malfunction. fuel pump relay, trottle body intake sensor not working properly. This sounds familiar. check the manufactor web site to see if there are any recalls. . hope it helps. duboff.
