Yes, I suspect she is fighting her pm nap due to long am nap (very common at this age)... this is all leading up to the 2-1 nap transition, which can start as early as 9 months.
If you have already tried to cut the morning nap down to 1 hr, then the next thing would be to cut to 45mins (you're spot on there!) and offer the pm nap around 3 hrs later.
So for your LO, I would try something like this:
6am - wake
9-9:45am - morning nap
1-2.30pm - pm nap
6.30pm - bedtime
If she's only had a short pm nap, then make sure you put her to bed earlier for the night but hopefully with the shorter morning nap, her afternoon nap should come back and be the longer one. This is the routine we had pretty much until we went down to 1 nap, around 15/16 months.
