Toshiba SDV398 VHS/DVD combo with built in tuner.
Everything works but occasionally it stops recording about 15 minutes short of programmed time. The clock keeps the correct time and the tape is new.

with a stop watch , check it is exactly 15 minutes to the second or just plus or minus 5 minutes say, for 1 , 2 and 3 hour records , also try with 3 hour and 4 hour tapes to see if there is a difference

the most likely reason. Either loss of friction in a slip clutch or wear in a pivot allowing a pulley in the jockey wheel assembly to touch the chassis, both situations when sufficient diameter of tape has built onto the take-up spool to trigger the loss of drive
It never fails on playback. Could there be some subtle transport load difference between record and playback?

void _-void-_ in the obvious place
My first VCR, circa 1981, had a timer problem connected with an incorrectly designed chip. If you set it to (say) start recording at 11:30PM and stop at
1:00AM, it would often quit at midnight.

So a divide by zero / year 2000 type problem with that one. I would have set the clock 12 hours out on that one, assuming only recording over midnight and never noon Perhaps the OP should take a careful note of times , assuming there is a timecode recorded , then see if there is a consistency in the drop out times at recording.
I just looked through my repair tips , maybe relevant
Ferguson FV21 Manual record and short lead-time timed record OK but failure of overnight record. Replaced the the 3 small electrolytics on the clock / timer panel and broke / inspected /remade all connections and also at someone's suggestion tightened all earthing point through-pcb screws on the various boards.Somewhere along the line must have effected a cure.
