Hi. New here and was hoping someone might have experience re: this issue. Truck runs fine but sometimes when I try to start it I got nothing. No lights. No starter. All electrical dead. After fiddling with the key, trying to turn lights on, playing with the steering wheel lock, it just comes back and starts fine. Clutch interrupt switch no longer in the equation. Also I find that after it comes back my radio has lost its program. I'm going to buy a Power Probe but thought I'd ask the forum first. Thank you for any ideas you can send my way.
