It sounds like the A/C compressor may need to be replaced as it sounds like it is bogging down the engine more than it should. This is not so noticable at higher engine speeds.

This is most likely signs of a worn clutch or throw-out/pilot bearing, inspect and change if needed. Hope this helps.

would you swap out a several hundred dollar part on someones recommendation sight unseen and then spend several hours replacing the part not knowing the whole time if this was the correct cure. Thats what your asking here because my first thought would be faulty fuel pump Any part will cost you over $100 bucks so why not address this professionally. Have it diagnosed correctly.

Sounds like an overheating problem or lubrication problem. If after it dies you can let it sit for a period to cool down it is most likely a cooling issue. Try removing the Thermostat and see if that seems to help. The thermostat may not be the problem as it could be the water pump not circulating radiator fluid. The reason it takes longer with AC off than with it on is because the strain on the motor is greater with the AC in the On position. Since you didn't mention an overheating issue it is probably a combination of a bad sensor and either faulty Thermostat or faulty water pump. Your also going to want to do a compression check on all cylinders to see if your running high compression on 2 or more indicating a crack in the cylinder wall or a blown head gasket. Lastly there is the oil pump, if that is not circulating oil correctly you will have a lubrication issue that will give you this symptom. If you haven't done so of late do and oil and filter change using gunk engine cleaner additive. This is added to the oil then the engine is run for 5 minutes, then drained. You have to change the oil filter when you use this as running the vehicle with this in the engine will damage the seals.
