how do you know it does not have spark if you cannot test it???

have you checked the fuel pressure??

Customer: replied 3 months ago.
I brought it to a mechanic shop when it happened and it died on him once and he's got to see that there was no spark to the spark plugs and then the truck started again
Expert:  roy replied 3 months ago.

if that is the case, either you have a bad coil that is breaking down when hot or a wiring harness issue.
