I was out fishing at a lake about an hour from the house when i get back to the landing i go to back the boat trailor down and the truck will not start. This is a problem when you get stranded with a trailer and boat in the water. The problem went away for a while then came back many months later when it came back it was coupled with the engine cutting out or shutting off intermittently so i could be in the middle of rush hour my truck shut off in the middle of standing traffic and unable to turn it back on. So far i have replaced the ignition module, ignition coil and ignition switch. The ignition switch has fixed the will not start problem but i have not been able to decifer the problem with the engine shutting off intermittently. I am going to try to replace the camshaft sensor next I read somewhere that may fix it.

This first happened when I was trying to get to a big college exam in the middle of an Indiana winter. It was well below freezing and my silverado decided it wasn't a good morning to start. I turned the key, all dash lights came on but when I turned the key to start nothing, not even a crank. I could hear relays and fuel pump engage but the truck wouldn't even try to turn over. I waited for my fiance to pick me up and I went to class. I came back a few hours later and it started right up. I would also like to say that it had a new optima battery, so no it wasn't the battery or connectors all clean and new. This problem would continue in the same manner for the next 6 months or so, the only difference being in the wait time before the truck would decide to start. It was mostly within 6 hours but lasted up to two days. I haven't had any problems the last 4 months or so but I live in the constant threat of it coming back. If anyone has a solution let me know.
