Blender now only has one speed and it's overspeed. Is there an overspeed govenor that causes the blender to automatically shut off? It will overspeed about 3 seconds before it stops working and all the lights start flashing.

Can you check it without the beaker on? It could be the blade seizing up, how free does it turn by hand?

Sounds like its overloaded. Feed it slowly

Important: This blender has an intelligent system that
automatically shuts off the appliance after 2 minutes
for speeds 1 to 18 and after 20 seconds for the PULSE
and CRUSH functions. If this occurs, the LED display
shows "EE"; unplug the unit and wait 30 seconds.

Mine does this as well... 5 seconds of operation and then OFF.
My guess is this is a fail safe where the blender is turning itself off to avoid overheating and what could potentially cause this overheating is the blender is struggling to turn the blades. What could cause this struggling of turning the blades I am guessing is a lack of oil in the blades rotating parts.
If you hold the circular blade part and turn it, you'll probably find that its hard to turn? Mine is... and I oiled it up a bit and found I got a bit more usage out of it... although only temporarily.
Ideally I need to pull it apart and oil it properly.

Contact the manufacturer of your blender, if the manual is around look in the last pages.

to see if its the Triac or just the off button perform this: connect the blender,while pressing the off button press the on button; if the blender stays on and you dont hear the relay function (Light ticky sound) maybe the off button get a broken solder point. But if the relay is functioning and there is no way to change the speed the problen is the TRIAC. This is a small piece on PCB with a heat sink
