7.3 IDI turbo misfire while cruising

[Trustyrusty]

Hey world, newbie here looking to ask a question that's probably already been answered. I just bought a 1991 Ford f250 with a 7.3 turbo and a manual transmission, truck starts up perfectly with a brand new starter and glow plug relay set. Yesterday I decided to have a little fun and give er some revs (all of them) and then I did some hard acceleration where it started slightly popping under load and then once I stopped accelerating and was just cruising it was still popping. So I pulled over to the side and turned off the truck and then turned it back on and that fixed the problem. Could this possibly be sticky valves? I'm not entirely sure since I'm new to the diesel scene.

Was the governor cutting rpms to 3500 or so?
These engines are extremely tough, but are much happier being worked and under 3k rpm......

May have been sucking air at the high revs and cought up after the restart. Or possibly a slightly clogged fuel filter that couldn't handle the pressure.
