It's possible only 2 or 3 cylinders are firing - due to bad glow plugs - and once warmed up all start cylinders working as they should. But it;s a strange situation - especially the manny tran - that 4 cyl is pretty simple.
But the engine will die a long slow death gradually losing more and more power and making it more and more difficult to start until one day it won't start at all. You could have some problems that are not noticable when warmed up. But hopefully its only the GP's. My 240D did that - started fine until one cold afternoon it would not start anymore - had 2 broken pistons & a bunch of broken rings. Have you checked your valve adjustments lately? Should be adjusted every 12k-15k miles. Out of adjustment valves can lead to a lossof power.
