Hi,
It does sound like you have a poor connection someplace. Check the ground from the ignighter to the circuit board. You might want to install a short wire to test it out.
The system works by applying voltage to the ignighter. The flame will conduct some power to the ground rod on the ignighter or to the pilot assembly. The circuit board measures this amperage, and if over 0.003 amps, it will leave the flame on. If under 0.002 amps, it should be shutting off the gas supply, and the flame will go off. At best, there will only be about 0.007 amps going through the flame to the ground rod or gas valve. So it relies on a good connection from the gas valve ground to the ignighter board to sense the amperage going through it.
GOod luck,
Fred.
