The shop tested the fuel pressure during one of its visits and said it
was okay.  It is so random it might have been fine during that test.
I would like to put a fuel pressure gauge on on it so I can monitor it
while driving but havn't figured out what to purchase and where to
install it.  I know it probably goes on the fuel rail or maybe I need
to install a tee fitting to make it work.

It has had the fuel pressure checked while in the shop.  It is in the
shop right now and hasn't stalled for them.  I recommended they put a
fuel gauge on it so when it does stall we will be able to see what the
pressure is at that point.

It began started stalling while driving about six months ago.     It shuts
off like someone turned the key.  Originally you could push in the clutch
and immediately restart it.   It used to happen once daily, most recently
twice a day.   It now takes about 10 minutes each time to restart.
Shutdown is random and there is nothing common between occurrences.

I had the fuel filter, plugs & wires, fuel pump relay, and EEC relay replaced,
the IAC valve inspected, and the MAF sensor cleaned.      The mechanic
said there is no error code. The vehicle is unsafe to drive in this condition.
Any suggestions are greatly appreciated.

The condition is typical of an intermittently failing ignition module.   The
failure doesn't set any code, and it is difficult to detect because it will
bench test good.   If you leave it in the tester long enough to heat up,
the failure sometimes appears.   Then if you disconnect it and it cools
down a little it will test good again.

When I experience this kind of failure I throw a $35 ignition module at it.
That usually does the job.   If not, I take it to a profe$$ional mechanic.

Good luck.
