My Father-in Law's 1995 Cadillac ElDorado, 148,000 Miles.
My father-in-law is an 86 year old German and he lives in Germany and drives a 1995 Caddy ElDorado.
Problem: While driving the engine dies. However after 30 seconds the car will start up again and run fine for a while, until the engine dies again. Repeat as necessary.
Brought in to Cadillac mechanic and they said busted sensor (which sensor unknown but it was replaced). However that did not fix the problem.
He brought it back to the Cadillac mechanic and computer said everything was ok. They kept it for a couple of days and test-drove it and nothing happened.
He picked it up and drove it for 14 days without any problems and then the same thing started again.
He thinks it runs hot 106°c (222°F) and Cadillac people say 108°c (226°F) is hot.
