I have a Z-248 (AT "compatible") that displayed similar "freezing" symptoms.
I got unreasonably high repair estimates (in my opinion), so I tried myself.
I noticed that a short power off time resulted in very short "on" time, and
a longer off time gave a longer on time; seemed possibly a heat related problem.
The 80286 chip was running VERY hot, and if I kept it artificially cool, the
machine stayed up longer without hanging.

For less than $50 dollars, I replaced the CPU, and it runs fine now.
