After new fuel tank, pump, filter, lines, ignition switch, temp II switch, a
few ground wire clean ups, and an adjusted throttle switch - things are
running MUCH better - BUT - I still have a problem.  After driving for a
bit, the bus will eventually stall and then have a really hard time
restarting.  Usually happens after I've driven it, get back in and I'm
idling to leave a parking lot (STALLS).  It's happened often enough that I
can tell when it's NOT going to restart.  The telltale sign is I don't hear
the fuel pump engage for those brief seconds when I turn the key over
(before I turn it all the way over).  If I don't hear the fuel pump, when I
turn it all the way over, it won't start.  I keep retrying it until I hear
the fuel pump cycle on.  Once I hear that, the bus fires up.  This happened
with the old pump AND the new pump (though the new pump sounds a lot better
when it cycles on - the old one seemed to struggle).

It happened today, and I tried replacing the fuel pump relay with a spare I
have.  When I put that relay in, the fuel pump just cycled on continuously
(not for the 3 or 4 seconds as normal).  It didn't start.  I put the old
relay in - a few more tries - I heard the fuel pump cycle for a few secs -
and it fired up and got me home.

I know all the FI parts are interconnected, so it could be a bunch of things
(O2 sensor, idle stabilizer, ECU??) - just wondering if this sounds familiar
to anyone, or if anything comes to mind.

Having fun learning how this machine works - but my machine is telling me
that I have A LOT more to learn :-)
