my car starts ok but after running for about a half hour or so and i stop and put it in park the rpm needle looks like the needle on a sewing machine, up and down up and down and i hear a loud squealing noise coming from the belt area but when i rev up the motor a few times all is well. if i dont rev it up the motor shuts off.

first try some belt dressing and checking the belts condition, next i woudl check for a bad IAC module causing the idle to go erratic.
