Pay attention to the voltage when it happens, do the head lights dim. You can also connect a digital voltage meter to the aux. fuse at the fuse box (hot side) an see if the voltage drops. To find the hot side turn the key to on, one side will have voltage an the other side won't. If you have a voltage drop then you have a bad/loose connection, then check battery,starter, battery connection wire at HEI. If its intermittent an happens quickly it could only be a voltage problem. Bad module in the dist. I bet.
