Stalling can be from a number of things, does the display go blank when it stalls?
Does it run rough before stalling? Gas smell?
Did you check all vacuum lines and ensure they were plugged/connected?
Ground wire to PC solid? Connectors clean with dielectric grease to seal them up?
Check other grounds on frame, etc...
Ticking can be the valves, exhaust gasket?, Pair covers intact, hoses plugged? (can allow valve train noise to be amplified)
When riding does ticking get quieter on declleration? Any exhaust popping?
These are things I would generally check over when I hear strange/new noises. They are easy to do before getting dirty.
