450SL Stalling When Hot (Yes, I Searched)
 

I have a 1974 450SL that's having some issues. She's a garage queen, 80k miles, but this means that she's parked for months at a stretch.

She starts fine, run great, idles nice. When she reaches operating temp, she stalls & won't start until she cools down. I've seached stalling issues for the last 2hrs, and have lots of options, but would like to narrow it down. Nobody seemed to have this specific problem. Any ideas? ECU? ICV? Does this model year have an MAS air sensor? I'd like to avoid a 'shotgun' fix!

Thanks for any info!!

Here's some info on the engine and injection:
