Shuts off while at idle and driving

My truck with start up just fine rev just fine. Like nothing is wrong with it. I will leave it there idling for some times 45 minutes and it not stall out. And sometimes it stalls out with in 20 minutes. Then I can drive it and it work just fine. Then out of no where it will stall out. Some times it will start right back up. Sometimes I have to leave it off for a little and then start it up. I have 58 psi on my fuel rail. Brand new coil packs spark plugs fuel filter. Mass air flow. My car is throwing no codes. But a evap. And that's my canister I broke a hose. I have no idea what it is. I have new throttle body position sensor. Checked my ecu everything fine there. Cleaned my idle control valve. Some times it will shut off once or twice then not shut off the rest of the trip. Someone is saying it's my TCC that my torque converter is locking up. But I never heard of it locking up and stalling then allowing to start then run then lock up stall then start back up run. Then not allow it to start. For a minute then start back up. Please help I done spent $1,000.00+ on mechanics and still have not figured this out.
