Have it scanned for live data and let us know what is returned.

Have you actually scanned for codes as not all codes will set a check light, check fuel pressure as well, start here.

Both hard and soft codes? Soft codes don't set the CEL. What about live data? The live data stream will give us the best idea of what is going on when this problem occurs.

P0110 is the intake air temperature sensor circuit.
Minimum acceptable fuel pump pressure is 34 PSI at idle. Recommended is around 40 PSI. It sounds like your fuel pump is quite weak.
