Well, I haven't managed to solve anything. Today, its running great. Couldn't get the symptoms to appear. Yesterday it started running crappy intermittently, so I swapped out the fuel pump relay with a spare. It still had the same issues, so I know the relay is fine.

I read the diagnostic codes:

A-1 was 3-1-3 A fault code for the PNP switch. I replaced that sucker about a month ago. I was really starting to act up.

A-2 1-1-1
A-3 4-4-3 ABS Pump motor, electrical or mechanical fault
A-6 2-1-4 Engine speed (RPM) sensor signal missing sporadically
A-7 1-1-1

I cleared all the codes and when for a drive. Car ran great, no rough running or almost stalling. Then I rechecked the codes and everything read 1-1-1

Its possible the issues arise only after the engine has been running for a while. Right now there's nothing to troubleshoot, but I have some important driving on my schedule and I have to get this cleared up.

Klaus, if you're there, you mentioned "if the pressure is positive, it is time to clean the PCV...)

Any instructions as to how to clean the PCV? ... Can a clogged breather system produce these intermittent symptoms?

Thanks.
