Runs and then shuts off

To me it sounds like you have a main power (constant control) relay that is worn and fails when hot or the ECM is going bad doing the same thing. Here are some guides and diagrams so we can see whats going on when the engine stops running.

Does the engine lose spark or fuel?

Here is a guide to check the main engine computer relay

Here is its location (below) if everything checks out I would get a used ECM engine control computer and plug it in.

Please let us know what happens.
