Engine shuts down at 60+MPH. Help?

[baker4]

02 4.0L non-flex. I hit 60mph & engine stalls, throttle is not responsive, then it all shutsdown. No engine light or warnings. I let it sit for a couple minutes and it restarts and acts like normal until 60 again. Any suggestions? Thanks.

Are you using the cruise control when it happens?

Have you pulled any codes yet?

thanks guys for asking

I just had radiation treatment yesterday and I have not been able to go for a ride. However, the cruise control is not being used and no check light goes on until the vehicle dies of course. When restart, no check lights. The day before this happened I had the emissions and safety test done on it for registration. I'm wondering if something got jarred or messed up by the tech, except we drove 2 miles on freeway with no prob, parked for my doctor appt, then it did it on way back home in less than a mile from hospital. I just haven't gotten any further than that with it. Thank you so much for asking!
