Use the turning signal blinkers engine shuts off!!

On my 01 Intrigue sometimes when I use my turning blinker the car completely shuts off. I have an after market remote start installed. I have been back and forth between my mechanic and they say its the remote start and the remote start place says take it to the mechanic!! I just had a security feature uninstalled, which required me to wait for two beeps before starting the engine. Usually when the car died before I had it uninstalled it could take 30 minutes to get the car started, while yesterday when it died I was able to start it again no problem. I also occasionally experience high rpms when I start the car and my abs will engage for a split second when I use the breaks when the road is dry and im breaking softly. Could this be my ignition switch?

Update! Now I when I go to start the car the lights on the dashboard and the gauges flash on and off blink and I have to keep trying to restart the car until the car finally starts.

Could be the ignition switch, but I'd say these issues are more than likely being caused by the remote starter. I'd have it removed.

Again I was having trouble starting my car and the only way I got it to work was with the starter.
