87 5KQ Quits After about 30 miles. Works after rest

[Matt Ammann]

Hi All,

My 87 5KQ, no turbo, has run out of stamina.  It seems
to quit running after about 30 miles or so.  If I let
it rest for
ten minutes, it will start up and run for another
while.

After letting it rest for a couple of months, then
replacing the
fuel and air filters, I was able to get a couple
hundred miles out of
it before it started crapping out again.

I've a working hypothesis that it is starving for
fuel, and surmise
that either the fuel pump is having issues, or the
fuel accumulator
has some sort of problem.  Any thoughts on things I
could check
out relatively easily?

thanks,
Matt
