Classic symptoms of a failing distributor 'assembly'... Common problem with 3.3 L Nissan.. Suggest full professional scan test to confirm before buying any parts!.. Those I have fixed exhibited the same thing.. Could start engine cold and literally watch it run rougher and rougher as it warmed up... This has been true on quite a few 3.3L Pathfinder, Frontier P/U... I'm not saying that is your trouble but sure has the same symptoms > except these would not recover once warmed up, they still run and could drive - but run rough...then after cold again, would repeat the same sequence.

i have access to a snap on "solus" and there were no codes present other than speed sensor what other things would they look for

First thing is engine misfire under 'Functional Test' > Misfire Counter... This is a multi component distributor and testing individual components I have found to be quite useless as it only acts up when heated!.. I've gotten so familiar with how they run with a failing distributor I don't have to do much testing!... Good luck with it!
