Hello, new member here but it looks like an excellent forum. I've just acquired a 1988 300E that starts fine when cold but sputters-out as soon as it warms up even a little. In 70 deg. weather, about 5 minutes or less. I have not dug into it yet but just wondered if this sounds familiar to anyone who might have a strong hunch.

I tried to do a search but the terms of my question are so common that I get a zillion random threads w/ either 300E/warm/dies/etc. in them. I know what an OVP relay is, what is an EZL? Where is it? TIA.
