Fred, it's so hard to diagnose an issue like this via the internet.

When you say the compressor flashes engine temperature, I understand this to be their SSAM system – with Shutdown annunciator light for high compressor temperature, high engine coolant temperature, low engine oil pressure and engine underspeed

That being the case, then obviously, the thermal cut out is shutting off the engine to prevent damage due to overheating.

The system is showing you an engine overheat situation, so I would look to the oil levels and I would make sure the coolant is topped up.

Cheers,

Bill
