Sounds like it's time to replace the ignition switch for starters. I'd also replace the fuel pump relay as it could have microscopic cracks that act up when warm. Have your electrician be sure to test the resistors and diodes right near that capacitor. Also have him perform a "shake and bake&qu...

It might also be worth checking the AIC (automatic idle control) valve for cleanliness and smooth operation. When the AIC gets gunked up, it can get jammed and cause stalling.

Shake and bake test is used by airline and locomotive industries. They literally heat and shake the part to particular specifications for a specific duration. For companies that didn't do this and caused deaths see WABTECH of Plattsburg, NY. They sent bad parts after their production manager went ou...

How old are the spark plugs, how old is the ignition coil, check your battery leads. As people mentioned above, loose leads can cause this, had this happen in my v70 while turning into a parking lot, it would get worse with load on the power system. Turned out the battery terminals have corroded to ...

That would be your first step.

Still no CEL on pos.II.

Battery terminals MUST be real tight or you are risking to fry some modules and alternator.
