Default Loss of cool air when gently accelerating

My 2001 PT Cruiser Limited temporarily stops blowing cold air from the air conditioner when the engine is under strain, not just the heavy strain that normally temporarily cuts off the cold air.

Any advice or suggestions are greatly appreciated. Thanks!

It's the PCM (computer) that controls this action by turning off the compressor to give you more power (you probably knew that) so the problem almost certainly is with the PCM. Have you tried resetting the computer by pulling off the negative battery cable? This clears up a lot of problems, it's like rebooting your home PC.

Also check that the engine fan comes on when you turn on the A/C.
