**Check the magnetic sensor (looks like a cassette deck record/play head),
sited near the inside rim of the platter. If it has a broken wire, or if it
is sited too far (there should be a fore and aft adjustement) from the
inside rim (where the magnetic information is recorded) then speed may be
erratic.IME, these things are pretty reliable, but I have seen the odd
sensor head problem. Be careful not to damage the magnetic strip.

I fixed a similar Denon (might have been the same model) which had a bad
drive transistor (TO-220 package). It was opening up emitter-base.
The turntable would run for a bit, then get erratic and even stop
altogether.
The coarse or fine speed adjustment pots are a more common (generic)problem;
often cleaning them will fix.
