Tin top problems
bit of a long shot before I decide to write off my car
sometimes the car will start perfectly, no problem at all,
other times I can turn the key to start and everything goes blank, the digital clock, the radio and all of the lights on the clocks. If I leave it for
about 30 seconds the clock comes back on but is reset and the time needs re-entering
Others Times I can turn the key and the engine really struggles into life, it could take 15-20 seconds of cranking to get it to spring into life
Ok so they are the problems when starting
then when i'm driving along all of the needles on the gauges will drop back to their resting position, the engine will cut for a fraction of a
second and will instantly come back to life (because the car is moving and keeps the engine turning over) but if this happens whilst changing gear or
stopped at the lights the engine will totally stop and then i'll have to crank it for a few seconds to get it to start
The car has electrical power steering and when it does its cutting out routine the steering can "lock", not like it is a non-PAS car,
almost like the steering is fighting me 
This problem is getting worse and worse, it started off not starting properly, then cutting out once a week, then the power steering problem occured,
now it is cutting out so often I cant get to the end of my street before the car grinds to a halt
i've had it on the diagnostics and there were a few faults that I knew about
P0601 - Engine control module memory check sum error
P0380 - Glowplugs malfunction
P0101 Mass air sensor performance problem
P0404 Exhaust gas recircuation range performance problem
P0110 Intake temperature sensor - circuit malfunction
U1601 CAN Network
P1555 Brake accelerate signal implausable
and then
1604 [2,6,16,4] Please refer to relevant technical manual
Any help or advice you can offer would be greatly appriciated, i cant bear the thought of getting rid of it but if i cant solve this one then im going
to have to

A main Battery terminal loose or wire to it broken within the insulation?
Is there a main battery or earth cable anywhere that appears even slightly damaged?
I did once have a similar problem where the main +ve batter cable to either the starter or from the alternator had come adrift and was sitting and
shorting onto the hot exhaust.. there's no fuse in that circuit so it causes some really strange faults. Things would die on the like the radio
or the wipers would stop working or it would drop to 2 cylinders etc.

What car is it?
Battery sounds weak - Do you know it to be good?

I've had cars do similar one was a bad connection at a terminal block that usually lost contact over crests (was fun with a mate driving loosing
lights over a crest while thinkin he McCrae he soon backed off)
another in work done odd things over bumps turned out to be a broken wire just where the main loom goes through the baulkhead think it fed the ecu or
something daft.
Another old fiesta broke the power feed to the ignition switch would only mess about when my mum was driving.

I'd be looking for a short or dodgy earth too.
That said, shorts are generally reported if they are sensor shorts, so that points to a supply/earth short (ie. alternator, starter cable, etc).
Presuming you've had no fuses go recently, that also indicates a main supply/earth short.
Check around all the hot areas where the wires are, exhaust especially. Then trace all the main feeds/earths from the battery around the engine bay,
paying particular attention where they pass edges of the panels or the engine.
If you're feeling confident, then unplug all the engine bay sensors/connections/battery and see if you get continuity between the +ve and -ve
main feeds.
Thinking about it, if it happens when you go to crank the engine, most likely to be a short around the starter solenoid/motor or their feeds.

Sounds like a vauxhall?
Id be going for dodgey/ damp connections either in main feeds or earth.
Dodgey alternater wires will do this.
Its be what evers cusing the can network code and the ecm code. the rest will probably follow as a result.
