Post 1989 jeep cherokee cuts out at high rpm need help have no idea!

so i have a 1989 jeep cherokke and the problem is it cuts out at high rpm and anytime you give it alot of gas i need help!!!!

ok i just replaced the fuel pump brand new, the cps, fuel pressure regulator. i have the fuel pump hard wired because thats the only way it will run. idk what it could be maybe a relay or some kind of sensor if you have any answers let me know because i need to fix this thing so i can go wheelin again...
