Ur-Q Problems this Morning - Bucking Bronco

["John Corbishley" <gtr1@traverse.com>]

My '83 has been great since the new timing belt in March.  Not missed a
beat.  Drove it home last night, not a problem.

This morning it started and idled fine, but once under way it keeps cutting
out at just over 2k rpm, then refiring.  The result was like riding a
bucking bronco!!

I was in a hurry so had to get in the '85 and go, but I did notice that a
relay was clicking under the dash.  It was not as cold this morning as it
has been the last two weeks, about 35F, so I don't believe that was a
factor.

Is this the dreaded fuel pump relay, or does it ring any other bells.

All input would be most welcome.

TIA
