Cuts out between 40-50 mph, usually about 1500 rpm and truck warm ? Any ideas on 2004 Dodge Ram 1500

Truck runs great except for that. No engine light on. Happens all the time but recently started but sometimes if rpms are higher when going from 40-50 mph it will not happen.

I just fixed a 4.7L Durango the other day with the same symptoms, no light. Just fresh on my mind for an idea.

What is your idea ? What ended up being the problem with your Durango ?

5 ignition coils, 1. 3. 4. 7. 8. Had to find them scan data scope test, watching them break down, no light. Happy customer.
