Last one to post in this thread wins!

sounds like a bad connection in either the switch or the ballast resistor
(provided you still have one)

next time it happens, jump the wires across the resistor and see if it fires
I was told it is probably the wire that runs right to the ignition switch from the bulk head so will hard wire it in. Trouble is it's a intermittent thing so it's a shot in the dark. Went out yesterday and started it right up 5 times at different intervals
