Thanks, Randall. You are, of course, right on about doing tests. Trouble is,
this has been an intermittent problem that can test fine at one moment or
another and I never know which state it's in at the moment!
Good news (:-p) is, now it starts and stalls right away. After a moment, it
starts again. Sounds like fuel starvation so checked fuel lines and for any
obstruction in the tank (none there). On the other hand, intermittently, when
I turn the ignition switch on, I get nothing. Other times, I get power but the
starter just makes a clunk sound. Other times, it fires right up. Sounds like
an electrical problem.
