    heavy plowing can bang elctric cables loose. check your battery ends for corrosion and tight bolts.

    then check the rest of the system with basic look over for stupid simple problems like rubbing loos wire ready to break off.

    i have seen a few ignition switches cause this on 94 and older gm trucks . thay are up on the steering shaft under the dash. had a guy with funny no start / sometimes stall out. we tryed most comon things. then i sugested the switch. he said go for it what else do i have to loose. poped a new one in still workin perfect to this day.

    took apart the old one. full of black junk dryed up lube grease. and super weak springs to make the contacts make conection.

    cheep fix that worked on a whim . Thumbs Up

    I have a 2000 Chevy 2500 same problem. Then one day it quit all together. Found out the positive cable melted to the battery and fell off. Replaced cable no more problems.

    If your battery terminals are fine you may have a short in your system. I had a similar problem on my truck and my rear blade cable was split and rubbing on the frame every once in a awhile.

    I had the same thing happen on my 78 for back in the day. It would stall or stumble for a second just like you describe, but start back up. On time it started to stall and I reach down for the key and when I touched it, it ran good. Wiggled the key a bit and it would cut out. Replaced the switch and all was good. I chased that for 2 years replacing fuel pump, rebuilding carb, tune ups, fuel lines ect. Try jiggling the key a bit to see if it duplicates the issue.

    I have the same problem on one of my fords 92 f250 5.7L. I was told all the above but what I have come to notice on mine is that while running the high power light mount and radio while working the plow heavily, the lights drag on the batt so bad. Now I only drive with lights and plow with parking lights on. Haven't had the problem losing power yet. Next is a daul battery set up or a real nice optima or such and a high out put alternator I think the alternator cant keep up with all the juice I'm eating up with my blizzard 8600sw.
