My 1990 Ford Ranger with a 2.9 v-6 extended cab, was not cranked for about a year. After replacing the battery and checking fluids, I got it to start up after several tries. I revved it to about 2500 rpm for a few minutes, the let it Idle and after about 5-min. it shut off. Next day I put a couple of gallons of fresh gas in and let it sit for a day. After a few tries it started up and I again revved it to about 2500 and kept it there for a minute of so, and it just died. It re-started easily enough but the same thing happened the second time. Suggestions have included new fuel and air filters, oxygen sensor, and possible water in the gas. Thanks in advance for all suggestions.

If the check engine light is on, you can extract the engine codes yourself, Here is how: http://www.freeautomechanic.com/diagnostictroblecodes7.html
I would replace the spark plugs only if it has trouble starting.
Aside from that. Start the engine and keep it running for about 15 minutes, this will allow things to warm up. And maybe after driving it around a bit, it may start to idle all on its own.
If it does not come around, replacing the IAC valve (Idle Air Control)is the solution.
