I activated the ＜Your Turn＞＜Once Per Turn＞ on P-117 [Veemon] when digivolving it and reduced the digivolution cost by 1. If I then activate this card's ＜Main Timing＞ effect and trash a card stacked with that Digimon, can I activate P-117 [Veemon]'s ＜Your Turn＞＜Once Per Turn＞ effect again?

No, you can't activate it. Even if a stacked card is trashed, the [X Per Turn] limit has already been reached for the activated effect.
