Why am I suffering from repeated flats same spot on wheel?
In addition to Criggie's suggestion, if the hole in your tube from your last flat is facing the tire, when you get your next flat; remove the tire/tube together from the wheel, put a mark on the tube and tire with a ink marker to record the position of the tube in the tire. When you find the hole in the tube, you will be able to correlate it to a spot on the inside of the tire where there may be a sharp thing of some kind protruding from the casing. Sometimes small sharp objects can become embedded in your tire but are not obvious. By narrowing down the spot on your tire where the flat occurred it will be easier to discover anything that could puncture your tube. 
Lightly and carefully run your fingers around the inside of the tire, sometimes you can't see what is killing your tube but you can feel something pointy. Be careful! 

You can use the same trick to focus on an area of your rim. Feel around carefully for burrs where the flat occurred, double check the tape, etc.
