Question about 1999 Ford F150 Regular Cab
Sounds like the hig head-pressure cut=out is kicking in and shutting down the compressor. This is probably caused by not enough air being moved across the condensor coil (in front of the radiator). Check and make sure all the engine cooling fan components are in place and functional (fan clutch, shrouding, belts tight) and also check the coil for obstructions (Bug accumulation, road debris, litter). Clean the coil and radiator as much as possible at a self-service car wash, see if that doesn't help.
This can also be caused by an overcharged system (too much Freon). Sometimes when these symptoms first appear, the knee-**** response is to add another can of Freon, only to make things worse. If this is the case, I would recommend a system evacuation and service, replacing the dryer/receiver and pulling a 28mm/hg vacuum on the system, and then refilling with the proper amount of Freon, and cleaning the evaporator coils as well. This can only legally be one by an HVAC Certified technician, to insure excess Freon is not released into the atmosphere.
Hope this helps you figure it out, and good luck!

The air conditioning is running off the power of the engine when you slow or come to a stop the idle of the engine now cycles the air control down cause theres not much power to run the a/c
the more power the more air will be circulated
now i was watching a jeggz infomercial a while back and they mentioned a little device to place on engine that keeps the a/c circulating at same temp even at a stop
some vehicles of higher quality come with this device but its not aftermarket its factory and its not from jeggz
overall you can order this device which name slipped my mind from the jeggz website
