250 Rebel Randomly Dies While Riding (only happens at night)

So about a month ago I got a flat tire on the old rebel and got the tire replaced. This took about a week so the bike sat in the parking lot at my apt for about that long. During this time the spark plugs and air filter (same as stock) I had ordered came in. Got those replaced no problem, put the tire back on when it was done and that night I test drove it. I got about half a mile away from my house and it died on me while I was going about 40mph. "Weird" I thought. Nothing looked wrong so I tried to crank it back up. It was turning over but wouldn't start. So I took the key out of the engine and waited about 5 min because I thought "Oh maybe I flooded the engine somehow." I put the key back in after this time and it fired up and I went right back home. Since then I have ridden my bike to work and on the way there in the afternoons it starts and runs completely fine, but after work at night it will die 2-3 times on my ride back just like it did when I first test drove it after replacing the spark plugs and tire. Each time it does this, I just take the key out, wait a min or two and fire it back up and ride until the next time it dies. This problem is super annoying and I am at a loss. Please help!

Sounds like either a fuel or possibly an electrical issue. Do you have an inline fuel filter installed? Remove the fuel line at the carb and let it run into a clean clear container. If there is a very slow flow (engine doesn't require much), or the gas is off color, it may be a fuel delivery problem, and the tank may have contaminants that are blocking the petcock/filter.

Keepin' all the left over parts. Gonna use 'em to build another bike!

Agree with flite, gut says fuel problem, easiest problem to eliminate from possibility.
day - night makes no difference other than temperature??
is one direction mostly up hill?
spent a couple of years with rust in tank so thick had to clean out petcock settlement bowl every couple of weeks when mine quit while cruising flat and level 45-55mph before I installed a new tank.. inline fuel filter saved the carb, used the biggest filter that fit..

Had a similar problem that would die as though key had been turned off once or twice every year..
started back up immediately though.. Must have run that way 6 years being it was so infrequent
before we get into any ignition diagnostics we would need year of your Rebel

Have you checked the new plugs? Are you riding with choke on at night?

I checked the fuel flow and it is fine. It has died both with and without the choke on; while at idle and while moving

Try replacing the plugs again. Use the old ones if you have them. Maybe the new ones are defective? I doubt it, but it is the last thing you changed.

Next time it won't start, pull a plug wire and check for spark.

I have seen small engines act like this. Usually it is a bad coil or sometimes old/bad gas.

Edit....Only at night....Is there any lights or such that you only run at night?
Check the battery voltage with engine off and with engine running.

Is that a thing that just randomly happens with spark plugs? They will just randomly stop working for 30 sec - 1 min?

RE:spark plugs

It is rare but I have seen cracked porcelain on plugs that gets worse when they get hot. The crack gets bigger and the spark shorts out.
They cool off and the crack closes enough for them to work again. Ignition coils do the same thing sometimes. Engine gets hot and it misses or stalls. Cools down and fires right up.

Fun to watch them at night...OH look at the pretty fireworks under the hood.

maybe someone at work screwing with you - taking the plug wires off and putting them back on loosely
