My guess (per pg 12), the electrode to burner gap is too wide...The electrode is both an ignitor and serves as a subsequent 'prover' (verifies main burner stays lit). IF out of adjustment, burner gas valve will then fail closed (a safety feature)...I had this happen on our RV furnace - same symptoms as yours...I my case, I pulled out the electrode and reset the gap from 1/4" to 1/8" and all was fine again...OR, the electrode (having two prongs) porcelain insulator (found on one prong only) may be cracked, thus shorting out. to determine, check prongs for continuity with base (continuity meter reqd).
