1996 Jimmy stalling Sign In

Hi all
I am starting to have a issue. My truck ( 1996 jimmy v6 vortec) has ran flawless, but all of a sudden I will be driving down the highway and it just quits. I put it into neutral and it starts up and can drive again. Sometimes for an hour or 2, and sometimes it will do it again right away. This is happening when the vehicle is warm and at highway speed.
When I am in town this rarely happens, it will only happen if I just came from the highway and am just getting into town it might just die.
I thought it might be a bad batch of gas, but it has happened for a month now. I thought it might be a new stereo that I got put in, but it still happens when I leave the faceplate off the stereo. I am at a loss of what to start to check what is causing this as parts for this truck are extremely high. It has had regular oil changes and has recently had a tune up.
Someone said it might be catalytic converter as I know my exhaust system needs replacing soon, would that cause the truck just to turn off?


Thank you for any suggestions.

Have the check engine light came on? Get a diagnostic scan done first....then if that doesn't show nothing,need to check fuel pressure and the fire at the plugs when the vehicle starts acting up....this is what I would do to start with.
