I was told if the computer was bad it would not even start as that controls injectors and ignition spark

ABSOLUTELY WRONG !!!!

A failing computer CAN allow the truck to start, run and then die.

Here's a little something to read:A9x ECM's (and same years ECM's) Failures Due to Age

Take some time and remove the PCM and look inside for leaking capacitors/burnt components.

I'll bet that's what you're chasing.

I thought I posted this earlier but I must have hit "preview post" instead.
