I had the same problem.

Check your plug wires and/or coil for arcing (at night).

Our starting problems and backfire were 100% due to the arcing caused by bad plug wires.

This is a very common problem with these cars when they get high milage on them. Like you said you used fuel injector cleaner and it went away for a bit... Your furl injectors need professional servicing or to be replaced because they are clogged. It only does it after a few minuteds becuase when the car warms up the ECM changes the air/fuel mixture and this is where the injectors cant keep up

Try a simple tune-up (including new fuel filter) if it's been a while since you have. Never replace expensive parts before doing regular maintenance stuff.
