Welcome to the forum Chris.
Whats it act like when it shuts down ? Like not pushing in the clutch on a manual, stepping on the brake pedal real hard until the enjun dies at the stop ?

Seems to me that the torque convertor clutch is not disengaging.
Could be a switch or it could be a solenoid or it could be a combination of both.

Pan needs to be dropped to replace the solenoid, switch too IIRC.

Thanks for the information

You need to put a scanner on it first to read the transmissions codes. Then go from there

I'm getting there!
Welcome aboard Chris! I agree with Marty and Jaryd, it sounds like the TCC lockup solenoid not releasing. best to check you codes on the PCM. if you don't have access to a scanner, you can pickup a cheapy bluetooth one a local wally world (walmart) or some of the auto parts houses. I bought a Micro Mechanic at our local walmart for about $20 and got an app called car scanner pro on my phone. the app that comes with the scanner is blah... car scanner pro works decent for most vehicles and will help you diagnose problems, also let you see live data.
the trick is to see in the live data if the PCM is commanding the TCC solenoid on or off. I'm not sure on 454's but I'd be careful, I have seen other engines get the crank and / or flexplate busted due to the TCC not releasing
even if you have one of the local auto parts houses read the codes for you, post up the results and we will be happy to help
