Does it do it all the time? Only when cold? Only when hot? At any throttle input? Only at full throttle? Only on inclines?

Need more info

Also, what have you done to correct the issue so far?

I'd suggest you fix it might run better. More info needed before anyone can help.

Start with the basics. Plugs, how old is dist' cap, rotor, cracked cap. Plug wires shorted melted. Low fuel pressure, lean out > can't deliver under load. Vacuum lines broken, off.
Did you do anything before this happened?
