After highway driving for more than an hour or so, and then slowing down or stopping, my 2008 Matrix seems to have no guts when trying to get up to 100 k again. I gear up as usual, but once in 5th, the gas pedal seems to have no affect and the car actually slows down as it would if coasting. I then need to shift into 4th gear to be able to get to 100k, and then shift to 5th gear. I use it for city driving mostly, but noticed this last summer on a cottage trip, and again this year. It has very low mileage. Has anyone else encountered this issue?

What is your shifting pattern?? Can you specify the gear versus top speed per gear please?? You can also specify which rpm do you upshift in???
It looks to me you are getting to 5th gear way too soon and essentially at such low speed, the 5th gear just simply does not have the torque multiplication available to pull higher (afterall, 5th gear in 1ZZ is the overdrive).
Assuming 100 KM is what you are going to accelerate to, using the gear ratios of 1ZZ you should be 3rd or max 4th until you hit 100 KM/H and then skip 4th and go to 5th to cruise at 100 KM/H.
