Maintenance/Repairs

My 1999 S-10 has some hesitation issues and my mechanic said I needed a new fuel pump. He put one on and since then the truck starts instantly when it’s cold but when it is warm and has set for a while it will crank for a while before it starts. Since then we have replaced fuel spider and regulator, fuel pump, cylinoid (sp) wire, heat sending unit, fuel filter and I still have the problem. I tried turning the key on before and hesitating before starting but that did not help. Mechanic checked pressure on fuel pump and that is not the problem. This seems to be a common with S-10 6cyl and there have been a lot of suggestions but as of yet no one has said that they have fixed it. Any suggestions or if you had this problem and fixed it I would be interested in what you did.
Thx in advance.
