Sputtering under load o r on inclines can result from:

Insufficient fuel delivery: Weak fuel pump o r clogged injectors can’t supply enough fuel under higher demand.

Ignition system faults: Worn spark plugs o r coils struggle under increased engine load.

Transmission-related issues: Transmission slipping o r torque converter problems can cause the engine to hesitate under load.

Air intake restrictions: A dirty air filter o r malfunctioning sensors MAF, oxygen sensor can cause poor combustion during heavy load.

Recommendation:
Test fuel pressure and replace fuel filter if necessary, inspect ignition components, check transmission performance for slipping, and clean o r replace sensors and air filter.
