Wont start or will stall

(1990 Buick LeSabre)
in West Fargo, ND on May 26, 2014
Car will start up with no problems, I will drive it around for a bit a shut it off. Will start up or will not start,when it doesn't start it will turn over but wont fire, or will start for a few seconds, but will sound like its misfiring or runs like hell and shuts off. If you let the car sit for half an hour to an hour it will fire up like nothing happened and the motor runs fine.

could a bad CAM sensor trigger the MAF sensor to go bad?

NO... I have been doing this for over 40 years... never had a cam sensor failure! .. However i am sure they do give some problems.. but i dont think it is YOURS!

so a bad MAF sensor can fail when the motor is warm. How does it start up fine when the motor is cool/cold then?
