2004 honda civic coupe. Shuts off when warm, cools down then starts again. It has a slight water leak, but nothing major. Doesn't overheat. Please help me if you can shed light on this problem

Probably temperature control sensor, if you have it. I have an import and it gave me issues recently. Not expensive part only labor is costly

PS a slight drip of water out of tail pipe is not leak. This is normal for cars to do this. Of course you would not use tap water as a coolant..

Thanks, I did some diagnostics and the temp control sensor and maybe the coolant sensor will have to be changed. I am aware of condensation but she said the leak was under the engine. Anyway I am picking it up tomorrow for $900. Thank you for giving me an idea for a starting point. I'm not very familiar with Honda
