Assuming your Accord has a tachometer, a lot of info depends on the tach's
behavior. If it drops like a stone when the engine cuts out, the ignition is
dying. The top suspect is the ignitor, although there are other suspects. If
the tach takes a second or two to fall, the ignition is still doing
*something* and the suspicion turns to the fuel delivery (like the main
relay). It is possible to have good signal to the tach and no juice to the
coil, though, so the chance taking the wrong direction on that is there.
I'd say 99% yes, since the vibration of the vehicle is what keeps the
flaky solder joints 'sparkin'. That's why the owner shuts it off, buys
cigarettes, and it won't start unless he smacks the dash.
Another thought: When the bad ignition switch on our '97 CR-V
manifested, I was on the highway going 100Km / hr when the cruise
suddenly disengaged itself . . . We'd only had the car a while so I
reset it and kept going. Three minutes later the tach (and speedo, I
think) dropped to Zero, and the engine died. Car restarted after a quick
look under the hood with a flashlight. Next manifestation happened in
city traffic, while trying to get out of an intersection.
Use google.com to search 'honda ignition switch recall' It happens
suddenly, no warning. It doesn't start to sputter or anything. Just
dead, wherever you happen to be driving. Restarts fine. VERY DANGEROUS.
