EZL QUESTION... 87 560sl stalls as soon as it reaches operating temp (+80c). WILL NOT RESTART UNTIL COMPLETELY COLD AGAIN. The cycle then repeats...perfect start first click of the key, idles or runs until +80c and then stalls instantly. Crank position sensor replaced ... no change. Coolant Temp sensor replaced, no change. Coil changed, no change.

DOEs this sound like failing EZL?
