Having a pretty big problem right now. The car keeps dying at random. Before it dies, the gauges flicker then the engine stops even while driving. It usually starts but ive had it die completely and not start up for 5 minutes before. After i start it back up if it does start, the A/C is switched off and the aftermarket radio i have disconnects bluetooth. I took it to a dealer and they had an "expert" look at it who said that either the tune, cam, or throttle body is bad. The car has had an aftermarket btr stage 4 cam & tune for over 4 years and the throttle body was replaced about a year ago. Any help is appreciated.
