Full throttle fuel cut and mis fire problem 850 1995

My T5R recently die while driving slowly after misfiring while idling when the engine is hot. It couldn't start again, had to be towed. The local mechanic clear the fuel line. The thing move again, still misfire and when I press full throttle, engine cut and couldn't run over 3500 rpm.
No special code recorded in A2 and auto box, no wire in A6 plug (is this normal? as heard others don't have wire in A6 before) so couldn't check if it is the cam position sensor, fuel pump or other problem. Any idea? As I don't want to replace the fuel pump as I am not sure if it is the cause.

    Ths camm sensor is only used during startup so that's not the problem. Did the mechanic change the fuel filter? Sounds like either it's a dirty fuel filter or bad fuel pump. Check distributor cap, rotor, spark plugs and plug wiring. Air filter could be dirty also.
