Gaming is for having fun. Fun requires clear rules.
If at the end of Suzy's second roll she has 3 dynamites a beer and an arrow for example, does her ability to gain life trigger (as her turn end was forced by the dynamite)?
Yes, as it clearly says that you still resolve your dice, so also related effects, like ability.
will it be able to give her life before the Dynamite takes one life
I'm not sure. I will try to dig more for this
