OM606A start probs when above 85C...
The lack of red/green is weird, but I'd still guess that the K40 is a possible fault. I presume that the red/green leds do light up with the remote is used to lock/unlock the doors?
Replace the K40 with a known good one. In theory, a bad K40 will stop the engine once the relay gets warm. But it could be that it is only failing when the stopped engine heat-soaks it.
