Engine dies at random. It will spin but not start for 5 minutes or so. Just replaced the ignition switch. Seems maybe to die when its warmer weather. Best I have read is main relay for next guess. whatever the part is also seems to control the brake switch because it also won't come out of park during the dead spell. Anyone agree or disagree?

 

its because its an automatic..

 

Changed the main relay and had no problems. Started and ran great. Now the key will not turn! How difficult is it to replace the key cylinder? being quoted around 160 for the new one. Will I still have to have keys reprogrammed as well? Any experience would be appreciated!!
