Deere 210LE Diesel PE4045TT092 Electronically Controlled Fuel Injection

[TractorTech]

My skiploader has an intermittent engine flutter. It starts and runs great, but at various times, hot or cold, the engine starts to flutter or miss. I turn the key off and start again, runs fine.

Dealership it was the ECU, didn't change. Replaced fuel supply hoses, filter and blew out the lines. No change. Maybe something with the pump itself?
