2005 Crossfire, 54,000 miles, battery less then year old.
been using gas from BJ’s big box store for 8 years. Last week used gas from WaWa.
while at stop light, car just died. All dash lights on. Turned off, put in park...started right up.
happened again today at very busy intersection. Both times while stopped at light.
Please advise where to start...any idea. Refuse to go to a dealer.
Thank you

 

Two most common problems I would recommend:

RCM and Crankshaft Position sensor.

 

only time my xfire simply 'turned off' --- O2 oxygen sensor
