John Deere 4 Series Stalling or Sluggish? The Likely Fix

This is a real-time DIY diagnosis and repair on the owner's own 4044M, which was stalling under load due to water and sludge contaminated fuel (traced to leaky fuel cap design). It shows draining the tank, removing and cleaning the pickup screen/fuel line with carb cleaner, flushing the tank, and refilling with fresh diesel and cleaner, plus a tools list. Good for owners troubleshooting similar stalling or fuel contamination issues.
