Problem with vehicle not starting

On occasion, after turing off the vehicle it will not restart. Very similar to a dead battery, nothing happens. After 15 to 30 minutes it starts fine. I have had the column switches replaced,battery and starter cked, all ok. My mechanic is unable to analyze the problem since the truch starts and preforms well. He has kept the vehicle and driven for 2 weeks at a time, but of course it never fails to start when he has it.

Does anyone have any suggestions?

I’d Definitely Take Off And Clean Both Battery Cables And Clean The Battery Terminals Before Reinstalling Them. Examine The Cables While You’re At It.

Thanks, I’ll try this.
