Just because the check engine light hasn't come on, doesn't necessarily mean that there isn't a stored code. And even though your car starts and all of the lights and radio and everything is working, your charging system could still be weak and causing driveability problems.
It's best to check the easiest things first.
Have the charging system checked and also scan for any stored codes. Unless you live in CA, any auto parts store can do those two things for you.
If you suspect the fuel system, change your fuel filter and then do a pressure test to determine the health of the fuel pump. It may, actually, be as simple as a clogged fuel filter.
