With intermittent issues, have to test when problem is ongoing. How long since a tune-up?
If it cranks good but won't start, have a helper crank it while you check for spark at the plugs, if spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. If your missing all three, check for rpm signal, comes from crank sensor.
If you can narrow it down to one system, we can test that one system. Any applicable trouble codes?

We can also check circuits for power windows.
Check the battery then if it's good use a multi meter and keep checking for voltage under the hood following the power wires it could be a fuse able link
ECU fried ? You could take a multimeter and troubleshoot all power-lines first to make sure there is voltage everywhere to start with / or isolate any shortage/breakage ...
