Ford E-250 engine quits and restarts after 30 minutes, shaking before shutdown on Ford E-250

Some Ford E-250 owners report experiencing engine stalls and restarts after approximately 30 minutes of operation, accompanied by shaking before shutdown. These issues may stem from problems with fuel delivery or ignition systems, leading to engine misfiring due to faulty spark plugs or fuel injectors. Additionally, the symptoms could be linked to malfunctions in the engine's sensors or electronic control systems, with error codes such as P0442 and P0456 potentially providing insight into the underlying problems. Some owners have noted that transmission repair issues can also contribute to misfires when the engine warms up, causing erratic behavior at idle. To resolve these concerns, it is advisable for owners to conduct a thorough diagnostic check, inspect critical components like spark plugs and fuel filters, and verify the fuel delivery system's functionality. Consulting with a qualified mechanic or Ford dealership is recommended for a comprehensive inspection and effective diagnosis of the stalling and shaking issues.
