Driving down freeway truck started sputtering on and off, seemed to bog down, filled up on gas and still continued to sputter on and off.. Started for a parts store to see if there was a code but died on way.. Had to get towed back to house.. Where do I start?

 

Welcome from Florida. Get the codes read. Try spraying some gas or starter fluid into the throttle body to see if it runs for a few seconds. If it does you have a fuel problem. You can also do a fuel pressure test.

 

if it doesn’t that mean a fire issue? No spark?

 

Correct, but reading the codes if there are any would answer that question.
