runs great then bad on 1990 Nissan Pathfinder

timeing dead on---cat converter good--runs great for 10 miles or so then starts banging out. Wouldnt even start after turned off tonight, 30 minutes later started right up and ran for another 10 miles and started bucking....fuel pressure? ignition module breaking down? any ideas greatly appreciated...thanks

Sounds like a intermittent fuel pump issue, need to have a tech check the fuel pressure and scan for any codes
