Hello back again, long time no hear from you.

The idea of the twig and the wheel sound, related to an engine quitting, sounds like a belt thrashing about as it shreds.

I doubt you would hear a timing belt from inside the cabin though.
If a timing belt was separating into small threads inside the plastic timing cover housing, anything is possible.
Most of the time the belt just snaps and the engine is dead.

I would advise pulling the upper cover, at the minimum, to check its condition with the cam and crankshaft timing marks related to the distributor number one wire terminal location.

The cam tensioner maybe going south on you. Combine the noise and it dragging could make for some slack develop on the belt teeth. You will have to spin the bearing it to check it out correctly for tightness and possible slop, of which is seriously doubtful with this type of bearing design.

In either case, the timing could have jumped and it would be the first logical place to look for trouble. The engine is doing all the bad sounds an engine can like its bad timing so go check there.

Has the car set all this time, since before April, with the same fuel in it?
It's got to be getting old by now.
I did not understand sentence about what you were saying about the FPR. Was it leaking fuel or just had pressure there?

From another posting,
The part about "only turning the key on" and hearing the pumps run for a second, should not happen on this car. It's a 2.2 LH and does not run the pumps until it see's a cranking signal from the distributor rotating.

All these appear suspiciously, suspicious! (:-)
