no start, no wait to start light

My 99 7.3 powerstroke dies after driving it a few minutes. Wait to start light does not light unless it sits for about 10-15 minutes then lights again and truck starts and runs fine. What could it be!

I am currently having the exact same problem. I reset the computer by unhooking batterys and replaced the IDM relay. It ran good with no problems for about 200 miles but is acting up again. Had to get hauled home yesterday. But now its starting fine. Its like all of a suddon the "wait to start light" will come on again and away we go. Sometimes 5 minutes sometimes longer. Did you have any luck finding the problem I am stumped and frustrated. Hope you can help and thanks.

I figured out that the reason for the intermittent "wait to start lamp" problem was that the fuse #30 in the fuse block located under the driver's side dashboard was loose. I had fog lights put in at a local supplier and they ran a wire straight into the fuse which streched the contacts and thus making the fuse become wobbly in the fuse block. Take the cover off the fuse block and wiggle the 30 amp fuse (#30) with the key in the ON position. Look at the "Wait to Start" lamp and see if it flickers when you wiggle the fuse.

If that is your problem the all that is needed is to solder the fuse to fatten it up and make it sit in tighter
