* Yields rise from near four-month lows
* Stocks rebound after ending below key level
* G20 nations accept Japan's easing program
* One suspect dead in Boston bombing; manhunt continues

NEW YORK, April 19 Prices for U.S. Treasuries slipped on Friday after a two-day rally left yields near four-month lows, with investors turning to riskier assets on news that major industrialized nations supported Japan's massive stimulus program.
Leaders of the G20 group of nations accepted that Japan's $1.4 trillion stimulus "is aimed at achieving price stability and economic recovery, and therefore is in line with the G20 agreement in February," said Taro Aso, the country's finance minister.
After a slide in U.S. equities this week left stocks cheap, the G20's support of Japan whetted investor appetite for riskier assets on Friday. But analysts said that with nothing else to back it up, that momentum fizzled out.
"A little bit of a risk-on trade overnight, but very little follow through with that," said Justin Lederer, an interest rate strategist at Cantor Fitzgerald in New York.
Prices for benchmark 10-year notes fell 7/32 to yield 1.708 percent, from 1.686 percent late on Thursday.
Thirty-year bonds fell 13/32 in price to yield 2.882 percent, from 2.8630 percent late on Thursday.
Still, yields remained largely within recent ranges, and analysts said there was little to break Treasuries out until markets have more certainty about growth in coming quarters.
Investors could also take their cues from equities markets and corporate earnings reports in coming sessions, as well as expectations for growth in the world's biggest economy.
U.S. stock index futures suggested a higher open, a day after the S&P 500 closed below its 50-day moving average for the first time this year.
"I think that probably Treasuries will probably react to stocks and the data will probably just play a little bit of a background" in coming sessions, said Thomas Simons, a money market economist with Jefferies & Co in New York.
In addition, the gap between the yields on Treasuries and inflation-indexed Treasuries widened after a sharp decline on Thursday, when a weak auction underscored how little investors are worried about inflation the face of faltering global growth.
The difference between the yields on five-year Treasury Inflation-Protected Securities and five-year regular Treasuries - known as the five-year inflation "breakeven rate" - was up 5.85 basis points at 2.01 percentage points, according to Tradeweb.
The 10-year TIPS breakeven rate was up 4.40 basis points from late Thursday at 2.31 percentage points.
The U.S. Treasury also plans to auction notes next week: two-year notes on Tuesday, five-year notes on Wednesday and seven-year notes on Thursday.
Also riveting markets was news of the hunt for the Boston Marathon bombers. Monday's explosions at the race sent bond prices higher in a bid for safety.
But police said one suspect was dead after a shootout early on Friday, with the search for a second suspect going door-to-door in the Boston suburb of Watertown.
