Driving down the road the truck shut off and will not turn over or anything just a thump from the drive motor on the starter, I was trying to turn it over and once it made a completely different noise than the starter drive are there any safetys that may cause the truck to shut down and the nutural start switch to disengauge or that wont let the motor turn over

Yes, there's a neutral safety switch, but the entire starter system is out of the picture when the engine is running. Stalling AND a failure to crank indicate the engine is locked up. That rarely happens without some kind of noise or warning first.

Started to mess with it last night noticed the radiator still had pressure in it and this raises a red flag because the truck has been locked over a month now. The starter trys to turn the engine you can see the crank move a little and if you put a pull handle on it and try to turn it and have someone bump the starter you can get to motor to move. Any idea where I need to start bottom or top end

You should be able to turn the crankshaft clockwise by hand with a socket and 1/2" breaker bar. If a connecting rod broke and caused it to lock up, that would not happen without you hearing a lot of noise first. If something caused a loss of oil pressure, the pistons would scuff and you'd notice overheating and a severe loss of power long before the engine quit completely. If it quit instantly, as though you had turned off the ignition switch, that is typical of a failed sensor, but that wouldn't stop the starter from cranking the engine normally.

Lets start with some electrical basics. Measure the battery voltage, then measure it again while a helper tries to crank the engine. Also, measure it with just the head lights turned on.
