Your main crank bearings and crank cap bearings are probablly worn well above spec which means that the oil flow is going throught them to quick and your not getting resistance to build pressure which means you need a motor rebuild

Dear Bill, You will need to find a mechanic who can remove the oil pressure sending unit from the engine block and insert a "real" oil pressure guage to tell if you really have a problem or not. Lots of factory dashboard guages are not very accurate over time. If you really do have that low of oil pressure, you need to address that quickly.

I have a S10 Chevy my oil pressure gauge going s back and forth 40 & 60 driving stopping somethings below 40

Could be normal.
Idle RPM pressure is lower than say 2000 RPM
You could replace the sending unit or have the actual pressure checked with a mechanical gauge.

Where is the oil pressure sensor lacted on a 1996 s10 2.2 Pickup

How much below 30 is it dropping? Oil pressure when in DRIVE at idle on a hot engine, is NORMAL at around 18 to 20 Psi. The warning lamp does not come on until around 7 Psi.

With that said, the oil pressure switch (for the light) is located on the lower left front of the engine. The fuel pump oil pressure switch and sender (for the gauge and fuel pump operation) is on the lower right front of the engine.

Normal oil pressure at operating temperature should be around 40 lbs, 30 at an idle. Either you have a bad oil pressure sending unit or you actually have low oil pressure that indicates a serious engine problem.

I have a 1987 gmc suburban and the oil pressure gauge at start up reads about 35 to 40 but after driving a while will drop to 15 is oil pressure switch bad

It depends on your mileage. It's normal for the pressure to read high on start up and then drop some but your numbers are a little low on start up, usually on the high side of 40-45.You could check your pressure with another guage and see if it reads any different. If it does then you should change yours. But if your mileage is running on the high side of 200,000 then it's probably wear and tear. I would be inclined to try a heavier oil, 15-40 or 20-50. This should bring the pressure up and help with lubrication. You could also add something like Lucas to your oil to help with lubrication and pressure. It's also possible the oil pump is wearing out but unless the mileage is below 150,000 it likely won't do much good and a new pump won't like the heavier oil.
If you are unsure of the mileage you could do a compression check. If it's 100 or under the engine is worn.There is still life in it as long as the numbers are close together but it is time to start thinking about the next step.

After 20-30 min. driving oil light comes on when stopped. oil light goes back off when moving again.

There is less oil distributed to the engine in idle position than when you drive. So when the oil light comes on, you may have to put a little oil in your car. While driving, the oil reading may be enough for your sensors in your car to not send a signal, but when you stop and the oil pressure goes down, it may not be enough and that's when the light comes on. When you drive 20 to 30 minutes, your oil gets thinner because it is warm. That also will send a different reading to the sensors. You may want to try a thicker oil (instead of 10/40 try 5/20 ... ask before you do this!).

I have stored in a garage and not started a 1996 Chevy Corvette

Hopefully you used a good fuel stabilizer before storage. Check your oil and coolant levels. If the car didn't smoke before storage, then you should be ok with starting it. If it did, you may want to spray a little dab of wd-40 or some other type of lubricant into each plug, or just remove airfilter and spray just a tad while starting, not really necessary, but can give you a little piece of mind. You should change your oil and filter at your first convenience, and when you do start it, run it for a good 20 minutes to burn off any impurities in the engine. Before driving, check your tires and air pressure. I would recommend changing tires if you see any signs of dryrot or cracking in the sidewalls before driving very fast(above 70). The rubber in tires will degrade over time, it is harder on them in storage than driving them.

Low oil pressure after engine warms up in 94 blazer with 4.3

I have a 99 blazer and ever since I have owned it, it reads lower in pressure when idling, but will go up too 40 while driving. This is normal for the vehicle. If the pressure gets real low, and stays low, it means its time for an oil change.

As long as the pressure goes up when you give it gas, it is fine.

Oil pressure guage intermitently falls to zero when idling. The dashboard "check gauge" light comes on. Has happened on three different occasions out of about 20 driving excursions. When it isn't happening...

My jeep also has started doing this. I replaced the oil pressure sensor. Sensor on the 4.7 is above the oil filter, follow the wires, typicaly is a 1 1/16 socket.
