Weird ac issue

Ok so yesterday on the way to work ac was working great as usual. Halfway there though the compressor shut off. Later that day I jumped the low level pressure sensor to diagnose it. The ac clicked on and worked great, i picked up a new one and swapped them out and the ac worked great again. Just to be sure I threw on the gauges and the levels seemed fine. Well again this morning halfway to my way to work it shut off. The compressor can be jumped via shorting the switch harness and it works great. Is it likely I got a bad switch or is there something else I can check? There is no evidence of leaks and the gauges read fine. Any thoughts?

Check your refridgerant levels again when cold. When cold, the A/C will kick on due to ambient temperatures not causing the refridgerant to disperse. Once warm, the low pressure switch will shut the compressor off to save it, as the lubrication is not enough inside the system.
