Folks:
My '87 Syncro Westie is experiencing some stumbling, hesitating, sputtering....

It occurs only after van has been run and then rests for a little while. After I
begin driving again (15-30 minutes later) as I drive, van looses power (ie,
accelerator pedal does nothing when pressed) and will slow to a stop, but it
won't stall - it seems to idle fine.

The "trick" I use to get around it is to press in clutch, turn key off then back
on, then pop clutch out - effectively coast starting it. It'll run for about 15
seconds with no hesitation and then go back into power loss mode. If I do this
for 5 to 15 times, then it goes away.

At first, I thought it had to do with water temp, but I don't know if it does,
as today temp guage went from cold white area to middle of dial and I was still
experiencing power loss.  Maybe it has to do with O2 sensor or Cat?

I've replaced both sensors on thermostat housing. I have replaced O2 sensor last
summer.

Any thoughts?
