Accords of this vintage have a crash protection fuel pump cut-off relay under the very left, lower side of the dash. The relay is a "one-shot, mono-stable mulitvibrator" type, and is fed by the same ignition low voltage pulses that drive the tachometer and by-passed by the starter buss on the ignition switch (powers the fuel pump directly). The cut-off relay failed on my '78 Accord in a bizarre way that somewhat resembled the symptoms above - the relay would become increasingly hot and sometimes would intermittently shut off the fuel pump. Eventually the gas feed would stop altogther. Sitting still for 15 minutes or so allowed the relay to cool down and start properly feeding the fuel pump electrons. Finally the relay quit altogether and I could diagnose the problem (out in the boondocks ). Fortunately I had a shop manual and some clip leads, so I fastened one to the fuel pump and the "parking light" drive in my trailor wiring harness and drove home with the parking lights on.
