Good afternoon,
How old are the ignition parts such as plugs, wires, cap, and rotor? That would be a good place to start.

I would check the compression to be sure there is no internal engine damage.

I would also check the fuel pressure to be sure there is sufficient fuel being delivered to the rail.
