Problem with my old, sold, 83.5 waterboxer:

After it has been running, if it stalls or is shut off, it often will
not restart for quite some time. Unplugging the ECU sometimes helps.
Letting it sit for a couple of hours always helps. It also will loose
power when going uphill, eventually dieing completely, only restarting
after sitting for a while. Other symptoms include running rich.

Coolant temperature sensor, fuel pump, and ECU have all been changed at
one time or another, with some improvements each time, but eventually
the vehicle reverts to the same old problems.

Anyone with any ideas, please respond off the list to:
