You need to check your oil pressure when hot, you will need a decent gauge that will screw in where your pressure switch is. By the sounds of it your bearings have worn and when the oil is hot (and at its thinnest) there is too much of a gap to maintain pressure.

There are two fixes for this, the proper one is to remove engine, strip down and replace all bearing shells, you will need to measure to make sure that your engine is running standard shells incase someone previous has carried out any crank work. You will then need to reassmble it all and refit the engine, its a major job and is easily 20 man hours of work.

OR

Put in a thicker oil...

Either try going up to a 20/50 oil or look at an additive, there is a really good one but the names escapes me right now, it use to be in a big white bottle and is used when building engines as well...

Check that the engine has a good earth!!!!

It's common f the earth lead to fall Off or rot away still think you have issues but make sure the engine block has a good earth

easiest way to check earth, stick a jump lead between battery -ve and the engine block, see if this changes anything...

Also as I said before get an oil pressure gauge on it, this is a definite must do before you start thinking of replacing any parts...
