Truck dies immediately after start.

I need help. First let me describe what's happening. When I start my truck, it runs for a few seconds then it just chugs out, it dies, as if it's not getting fuel or it can't breathe. This happens very rarely though, like once every two to three months. After it dies it usually dies one or two more times, then either I can pump the gas and get her going or it won't start at all. If I get it started it starts and runs fine, no hiccups or issues for another several months. If I can't get it to run right then and there, I walk away for a few minutes, 5-10 and try again, at which point she fires right up and runs great for several months. What the hell is going on? I called the dealership and the chuckle head I talked to in the service department said he couldn't even venture a guess as to what might be causing this, said he's never seen or heard anything like it in the 8+ years he's been working there and told me I could bring it in but if it didn't do it there I was pretty much SOL. I politely thanked him for his input and hung up. My truck isn't throwing any bits, no lights, it's an '08 V6 4x4, I just turned over 125,000. Please tell me someone on here has seen this or at least has some ideas. Thanks in advance for your help and concern.

Have you tried cleaning your throttle body? My wife had a Mazda 6 that did something like this and once I cleaned the TB, it drove like normal.

Might not be the issue but it's a good start.

 

I'll give that a shot, thanks
