Yes it will. Your having to depress the fuel pedal more and force more fuel into the engine. Eventually the engine will just stop running because the exhaust cannot get out.

not hills , do tell on the road performance.
ive driven vast cars , trucks and motor cycles up crubs
and everyone needed the clutch slipped. at 0mph.
low power has vast cause but in pure physics
short list it physics,
longer is tests (1 to 10 tests)
then 50 causes !
physics, 101 Petrol gasoline (good gas tops my list)
1: engine bad, low compression, on any cylinder,
1b: cat converter melted or EGR stuck wide open,
2: weak or bad spark or timing wrong on any cylinders; scan it yet?
3 bad fueling, (too lean, or to rich and misfiring)

1,2,3. scan it yet?
I'll not attempt to do the list of tests.

Does the driving on overdrive mode cause high fuel consumption, because the transmission use the first three ratios mostly?

driving in over drive mode actually is what gives the economy as the engine rpms will be around 300 less than direct drive . Lower rpms = fuel savings
OD should come in around 60 klm/hr and drop out at around 50 klm/hr. When you are accelerating hold the pedal in a set position and watch the rev counter (rpms ) and each gear change you will see the rpms drop and then build back up as the vehicle speed increases At 100klm/hr the revs should be around 3200 rpms or less but if over ( say 3500 rpms) then may be the OD is not coming in. One way to test a box operation is to find a speed shop with a dynomometer and test the gear selections against loads and engine rpms

1996, eg falcon, auto, van, original 105000klms, just stops randomly, whilst driving. After sitting on the side of the road for, between 5 and 30 minutes, it will go again as if nothing has happened, might...

run fault codes for starters. check the cat converter as it may be broken inside and blocking up the exhaust pipe. Regular happening for cat converters.

Hi usage on petrol

Take the vehicle for a scan there must be an error reporting issue that has caused the increase in fuel consumption.

I don't know if this is what you're after, but I am getting my Mazda 3 today, and through my research to find one, I learnt that, according to the manufacturer, the fuel consumption on it should be 8 - 8.6 liters per 100 kms. I don't always know how accurate these are, so, I usually just fill up the tank, zero the trip, and after my next fill - km / liters to fill tank. 10 km/l is pretty average, anything above 10 is good fuel economy.
