Help me with AC issue

I’m hoping someone can help lead me in the right direction. Last weekend we are at the same campground we are this weekend and her air-conditioner worked fine. We pulled in today around 230 with temperatures in the upper 80s. After hooking everything up I turned my fan on first and then turned the controller to cool. I didn’t think I heard my compressor kicki in.. After about three minutes I put my hand by the vent and it was still blowing warm air. I then turnedmy fan to auto thermostat in the off position. I then turned it to cool and nothing happened. My thermostat was set at 72. I bumped it down to 50° And the compresso kicked on and off about three times then kicked on again ran for about 15 seconds and turned off. I let it sit about five minutes then went back in andwith the thermostat still in the auto position turned it on to cool in the air-conditioner started working. After 10 minutes it popped the breaker on our 30 amp service. I reset it and it ran for another 10 minutes. Long story short, the neighbor and camper let me borrow his 50 to 30 amp cord. Plug that in and it worked fine for about 40 minutes until my camper cool down to 78° And then the air conditioner turned off. The thermostat was set at 60. I turn the thermostat as low as it would go in the air-conditioner kicked back on. I did put a thermometer where the air was blowing out in the coolest here I’ve been able to get is 52° with the inside temperature being 82. Does anybody have any ideas what will you be going on
