1977 Campmoble (Named Tiki) mostly stock.
2.0L with stock FI (78 engine w/ hydro lifters)
Battery about 9 months old.
Starter (Bosh) replaced about 6 months ago.

About a month ago came out of church (6pm) turned the key,
dash lights came on, continued to turn key to start and lost all
power. All dash lights went off and nothing happened. Turned
key to off position and then retried. No dash lights or click.
Checked for power on radio and had lost all settings. Radio
light flickered as if sporatic power. (Radio wired hot all the time)
Checked Battery Connections, and Starter Connections. All good.
Checked the fuses (and turned them to ensure good connection)
and they were good.

Checked battery voltage with meter (12.65v) continued to check
all the connections again and retried to start for about 20 minutes.
All of a sudden Tiki starts and runs fine. Drive home quickly.
When get home check alternater voltage (idle 13.59v / rev 14.57v).
Turned her off and she restarted no problem.

Been doing fine for the last month as a daily driver.

Spent the night at my Mom's house in Anaheim, CA.
This morning turn key and lost all power again. Dash lights came
on but all went away like before when I tried to start her.
Again checked all the connections. Checked Battery (12.63v)

Have checked and cleaned the battery posts & cables.
Checked and cleaned the connections at starter. Even replaced one of
the starter connectors that looked questionalbe.
Love tapped the starter and solenoid.

Even tried leaving the battery disconnected for 30 min.

Reconnected battery (12.35v). Tried radio, it flickered as if the
power fluctuated. Very faint door lights. Tried key to on posistion.
No dash lights. Turned key to start but no dice. Did hear faint sound
for a second. Tried love tapping the starter again. Tried to start her
again but still no dice.

Help! Not sure what else to try. Gonna have to ride the bus
to work until she's fixed.
