The O2 sensors won't cause this. Also, a needed tune up isn't going to cause these symptoms. What it sounds like is you have a faulty crankshaft position sensor. Take a look through this link and let me know if it mirrors what you experience:
What happens is as the sensor gets hot, the circuitry in the sensor fails. As a result, you lose spark to the engine. You could check for spark when it doesn't start to see if that is the cause. Or, using a live data scan tool, you can check for an RPM signal when cranking with a no start.
If you determine this is the cause, here is a link that explains how in general one is replaced. It isn't hard on this vehicle.
The location of this one is a bit different than the one in the link. It will be right above the oil filter. See pic 1. Only one bolt holds it in place.
If you feel confident in replacing it yourself, it should take about 15 minutes. Once the connector is disconnected and the bolt is out, gently wiggle it back and for while pulling outward. It will come out, but be careful not to break it. Before installing the new one, make sure the port is clean that it sits in. The new sensor will have an o-ring on it Lubricate that o-ring with a small amount of oil before installing it.
Align it so you can reinstall the bolt and connect the wiring to it and you're done.
Let me know if this helps or if you have other questions.
