truck won't crank after it gets hot
 

I have 1993 w250 extd cab 5.9 diesel. after it runs for about 45 minutes and I cut it off, it will not crank(no power to starter) til it cools off.Any advice would be appreciated. Thanks!! tcb1

Check teh starter relay, moounted on the inside edge of the drivers fender, near the battery. I had many problems with starting caused by a failing starter relay. Might also be a fusable link?
