Any suggestions on why my car 99 Cadillac STS keeps cutting off after I come to a stop with no warnings? Normally just starts right back up, once it took approximately 3 tries to start up.

try to change the throttling positing sensor it not expensive it about $30 bucks and easy to change

have the codes scaned, the no warnings to me would indicate crank sensors, do not replace the tps

My 1999 Seville STS was doing the same thing. Finally it cut off and wouldn't restart. Had it taken to the dealer and they found the problem to be in the ignition switch. After the switch was repaced it hasn't happened again and it has been 2 years.
Hope this helps.

hey cliff wanted to know how much that ignition switch ran you?
