Not sure what else to call it. Today the truck was running great when I stopped to get something to drink. Got back in the truck, and it turned over, but wouldn't start. I checked all my fuses, they were all good. After almost an hour, I tried it again and it turned over and I let it go longer than normal and it fired. It runs great, just it is turning over longer than normal before it fires up. What could it be? I am afraid I am going to be out and it won't start at all. Thanks in advance.
