Sounds like hinge binding at the w/s on the hinge side. Take a dollar bill and insert it at various places around the door as you close and see when you can't easily pull it out. ribbon works too. And for the final analysis place a dab of soft clay on or near each hinge. It will smash down but should be at least 1/16th' when you go to peel it off.

You need free clearance at every point or the door is binding. How to shim hinges for better closing can be found on YT or I can walk you through it..

BTW, for the archives, half the time one only needs to snug up the hinge screws. This does not sound like your problem, but check them anyway.
