What is the most common cause of a grabbing clutch? on 1993 Mazda B2200

Issue occurs in 1st and 2nd gear, where the grabbing or stuttering action happens upon releasing clutch. Have had slave cylinder replaced approximately 2 years ago; cracked manifold replaced 1 year ago. 135,000 mi. 2.2L, not FI. Clutch fluid level checked 1/mo., full.

Also a defective pressure plate could cause this but clutch removal/inspection is required for either Roy's suggestion or mine.
