Our 86 stanza wagon runs good cold and after it heats up it has no
power at. Jerks and cuts out. We have changed about everything
possible. Throttle position switch and even ecu. No change.
Anyone have this same problem. Any advice would be greatly
appreciated.

if it has the throttle body EFI setup, might try the MAS on the side of the
TB unit. Seen these cause those sorts of problem and never set a code.

This may not be your problem but it is very easy to inspect for. Check
for cracks in the molded air hose that runs between the airflow sensor
and the intake manifold, specifically at the root of the convolutions.

I had this problem and replaced fuel filter and oxy sensor. Was about to
replace spark plugs, but when I examined them the looked like new. So, when
the car quit running I had it towed into a shop. They replaced the spark
plugs and it has just run better and better. It seemed like it had carboned
the cylinder heads to a point it was firing at wrong time and just quit.
These take 8 plugs. Replace them all.
