ruud ignitor problems

sometimes the ignitor will glow and sometimes it wont .... when it does glow the furnace lights and shuts down fine .... when it doesnt glow the furnace senses no flame and blows for a bit and then shuts down ( if i light with bbq lighter the furnace runs fine again) ... this isnt good i know because whatever is stopping the ignitor from working could be safety related...... Im guessing the ignitor is good.... I have probed the plug terminals from the control board for the ignitor and when the sequence tells the ignitor to glow it only shows 11.something volts .... what is prob wrong??????????

Probably the circuit board if it's only sending 11 volts to the ignitor instead of 120.
