Sounds fuel related. We could start by making sure the fuel is present and the (is it twin carb or fuel injected) is behaving itself. I assume this happens when the car is cold?...and can point to a choke or heat-riser issue- twenty seconds..eh? Does it seem starved of fuel, or choked off with too much fuel? a sniff of the exhaust when this happens would let us know. 1988 still has twin carbs??

Fuel injection then, obviously-...achem, I have no friggin' clue. Sorry for wasting your ions then-

How's the coil doing? sounding like an electrical difficulty if all is 'skippy' with the fuel circuit.
