A/C cut off pulling a load, will not come back on until restart.
All fuses and relays seem good, system uses a independent vacuum pump connected to the can. No leaks.

Good morning.

Do you mean the vents change position or the compressor stops working?

No, truck has a separate vacuum pump that is not effected by manifold pressure. A/C stops working.

Okay.

Is the compressor engaged when this happens?

Can you give me high and low side readings?
