Temporary no start

[spldart]

Road about 22 to 23 miles towards home. Stopped off at my storage room to pay a bill. Bike restarted just fine. I head down the road a half mile to the grocery store to pick up some I load the bike up and attempt to restart but the motor just
turns over but wont start.
>got gas? check.
>got compression? check.
>got spark? I dunno as I didn't have my timing light there at the grocery store.

Tried a push start. Nada...
Shut the key off and thought for a bit. Thinking *well damn. I'm gonna have to push
this thing another .6 miles to the house*

Turned the key back on and hit the starter and instant fire. Ran fine to the house.

An aside. It dropped dead at a stop sign this morning but ran fine for miles after
that.

My thought is electrical.
Are there common places in the harness known for faultering?
Are there other common problems to cause intermittent loss of spark <---
that's an assumption as to drop dead in morning mid operation and no start
in the evening....
