Engine Shut Off Without Warning problem #1

Bought auto 2003,after 3mo auto engine would shut off without warning at any speed,highway or in driveway. Took auto to dealer and auto kept for 3 days and dealer unable to duplicate problem. Took auto back 5 other times and same results each time. Complete tuneup was done that cost over $500. 00 dollars ,vacuum hoses replaced,ignition inspected ,complete computer diagnostic electrical component checks. Auto still dies without warning. Sometime within 2wks and sometimes within 2mos.

Engine Rattling And Whining Sounds problem #2

When I first purchased the car it had a cracked head and many other minor problems. I repeatedly brought it back to the dealership and they told me that there was nothing wrong with the car. I am still experiencing a "check gas cap" warning and I hear a clicking noise coming from the rear right side everytime I apply the brakes. Also I hear a rattling noise everytime I hit any size of bump.
