You need to check if there are any bubbles in the pump basket. Bubbles mean the pump sucks air, not water. Fill vacuum hose with water before you attach it. Push it down from vacuum head so that the water rises up the hose and then you can attach it.
Check for bubbles with the pump running and without the vacuum hooked up.
It could be due to suction side leak. Meanwhile, you can DIY, if needed, basket lid o-ring, inspect, clean and lube it well. With regard to the pump drain plugs, remove and reseal them. Ensure that the skimmer weir is working freely. Check that the water level in the pool is not creating a vortex.
The plumbing contractors in Toronto say that always put the swivel end of the hose on the vacuum and not the skimmer. Also, check for the pressure when before and after you start vacuuming.
Now, the suction side leak is a leak in the pipes that go from your skimmer back to the pump area.

Anyone still interested in the outcome of this. The Chlorine tablet feeder was installed backwards. With full suction the water could hold the column of tablets up enough to pass some water thru even though it was pointed in the wrong direction. Plug in the vacuum hose, not enough suction to hold up the tablets in the tower, so they dropped down, plugging off the flow. Uninstalled and reinstalled the chlorine tablet feed tower, everything works perfectly. Bottom line, chlorine feeder installed reversed to the water flow.

Congratulations and thanks for posting your solution as it helps others with the same problem and gives them something to check
One thing I would like to point out if you are not aware is that continous use of stabilised chlorine tablets will raise your CYA level so high that your chlorine becomes ineffective and you have to dose higher to maintain correct sanitation levels as in Chlorine / CYA Chart relative to the recommended Pool Levels
For every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm.
For every 10 ppm FC added by Dichlor, it also increases CYA by 9 ppm.
For every 10 ppm FC added by Cal-Hypo, it also increases Calcium Hardness (CH) by at least 7 ppm
