Changing the wires, plugs and coils should help no matter what.
It may be a fuel filter starting to clog. I had that on an old Ramcharger. It would drive fine for about 20 minutes, then I would have to pull over and let everything settle. then it would run fine again.
The difference being the truck had a sock style filter and our cars have a canister filter.
You could try to run some Sea Foam through the gas or have the injectors cleaned.
