1750 goes to sleep

[James Cook <james@domain.elided>]

Hello all,

Diagnositic help please.
Was cruising along the other evening at a brisk pace and began to feel a
subtle loss of power. I was at about 4500-5000 rpm, it felt kinda like
someone was grabbing the back of the car and holding the car back just a
bit.

After a bit the hesitation returned and after 10 minutes or so of increasing
recurrance, the engine quickly (over 10 seconds or so) reduced its power and
died. Waited a minute at the side of the road and looked at this and that,
but could find no obvious problem. Oil pressure still good, lotsa battery,
fuel pump quite audibly pumping.

Restarted and drove 100 yards with very limited power and she died again.
Waited and restarted a third time and went to a gas sation where I waited
about five minute with the car idling. Then I drove home like a banshee on
the highway (30 minutes) with no trouble at all - actually ran like a dream.

Had the same problem last fall one day, and next day discovered the fuel
line was cracked. I had that fixed and the problem went away, so I assumed
that the crack in the fuel line was admitting little air blips. Now I wonder
if this may not have been the case.

Any thoughts? Anything I should check for that might give a clue?

Gratitude.
