HELP, WON'T START

I have an 86 TC 5 speed. Suddenly it won't start. Seems to be getting fuel, fuel pump runs, also have spark. No check engine light but haven't run any codes yet. It did start after about 15 min of cranking, drove for about 10 mins then just died. Smells rich but unsure whether it is spark or fuel problem. Please giveme some ideas.

Pull and read the plugs, check fuel pressure.
