'92 525i cuts out when hot

bmblues · 11-21-2007, 07:12 AM

Hi there
My '92 525i manual runs perfectly until the engine warms up. When the water temperature gauge hits the half-way mark (supposedly ideal operating temperature?) the motor cuts out and will not start again until it cools down.
Could it be a faulty sesor of some nature? If so, where do I start looking & how do I check? I am not accustomed to such comlex & sophisticated management systems & am a little overwhelmed! Can any electro-mechanical gurus help.......PLEEEEEEASE?
