every now and then it'll cut out completely losing all power, normally happens in traffic and when it does happen i get a check engine light and a flashing sport mode light. car wont start for about 20 seconds take the keys out the ignition and back in and its back to normal again. the guy i bought it from had an aftermarket immobilizer put in so i have to carry around these two small black dongles on my keys i was thinking it might be something to do with that maybe
any help is appreciated
