Can I put an oil based siding stain over acrylic paint that is on cedar shingles? I will be lightly sanding first. Want to put on the most durable coating (longest lasting)...house is on the water in Maine.

Stain needs to be able to penetrate the surface that you are putting it on, in your case the cedar siding. If there is something in the way, such as paint, it will not soak in to the surface, resulting in the stain not adhering at all. In some areas it may stick, but it will not stay for very long. Simply sanding the surface will not do. You will have to strip off the paint with a stripper. However, staining is going to be the most durable if the surface is prepared correctly.
There are a few more options as far as what you can do. If you would like to paint your siding, you can use an exterior oil based paint right on top of your current paint. As far as painting, this would be the most durable option.
Another option would be to prime with an exterior oil based primer, and then use an exterior, latex based paint.
No matter what you apply, make sure to cover your plants around the house.

Are you asking if you can put a solid hide oil paint or stain over an acrylic primer? If so, why would you want to do so? Acrylic paints and stains have a couple advantages over oil products: They are much more color fast, as they do not oxidize, leaving a dusty coating on the surface. Further, acrylics allow the house to breathe better than oil. When the house cannot breathe, it peels!
As Christine has stated, the wood has already been sealed. An oil product will no longer penetrate, especially over relatively new siding. Were the siding old and badly weather, the situation would be different. Here I often primed very dry cedar siding with oil primers and then used an acrylic top coat.
I long ago converted to acrylic solid hide stains precisely because the oil stains would not hold up, even over a relatively short period of time. I would return a couple years later to find the oil stains very blotchy looking.
