I’ve searched the site, but have not found a good match for the problem...

1994 222K, Banks Git Kit and air filter installed 2 years ago.
Prime_Loc Remote Fuel Filter System. Fleetgaurd fuel filter (changed every 20K)
Fuel return line replaced about a year ago with braided steel racing line.

A few days ago I parked (engine off) for about 45 minutes after having driven about 10 miles. The truck has always started immediately, but it took about 3 seconds to crank. It then ran very rough. I pulled out and the sputtering continued. After about a mile she hiccoughed pretty heavy twice and then all was well.

I have run her about 30 miles since and no problems. But I am wondering what the cause was: a symptom of some serious failure about to occur, or just an ephemeral problem due to contamination either from the air intake or in the fuel line.

Any suggestions appreciated..
