Where's the OVP in a '92 300TE 4matic?

[Fintail Fan]

My 300TE's curious tendency to stall at slow speeds and in the middle of intersections after starting from a stop, has now grown to include failing to re-start, (engine turns over, but just won't catch), even when it's been purposefully turned off, such as doing errands on a Saturday afternoon when the engine is still somewhat warm, or cold. In the times when it stalls while driving and the engine is hot, it may take @ 2-3 tries to get it started, (one or two light changes, which is not only embarrassing, but dangerous), but when doing errands, and the engine is warm or cold, it may take minutes or hours before it will restart. As I write, it has been two hours and it still won't catch.

I'd like to diagnose and repair this myself with the help of this forum, as I can't continue much longer with the car in this unreliable condition. If I can't fix it myself, I will have no choice but to take it to the dealer for who knows how much $$ to repair, which I would certainly like to avoid if possible.

All my searches have pointed me to the OVP as a likely culprit, (yes, I know it is blamed for everything), but since the car doesn't suffer a rough idle, hesitation, or any other symptioms which would indicate a possible fuel delivery problem, I pinning my hopes on this as the cure. Please correct me though if you think or know differently though.

If anyone has a photo, link, or can simply explain to me where to find the OVP in my car, what it looks like, whether it has a fuse, and if so what type, where it's located, etc., I will be especially grateful. Thanks.
