INTERMITTENT Dying after Startup!

[Air&Road]

My '88 300E has developed the old "no idle after start up." In the Bosch Fuel Injection troubleshooting chart there are several items that can cause this, and I will work though the test procedures for each one.

My question is; which one of the items could be INTERMITTENT? I typically associate intermittent symptoms with either loose connections or electronic circuitry.

The car starts great and runs great. Sometimes when kicking it in neutral to coast or to idle at a stop light it just quits. It will start right back up, but you have to rev it a little to keep it running.

This happens sometimes when cold, sometimes when hot.

I'm just starting on the troubleshooting process which is always a challenge when the problem is intermittent.

Thanks for any experience you might be able to share.
