idle for a couple minutes

[TRICKY1121]

have a 2005 Yamaha vz 225 hpdi. it will crank up and idle for a couple of minutes and then just die, it will usually restart but then die again. changed the filter, drained the vst and cleaned the screen, replaced one of the low pressure fuel pumps just to see if it made any difference. no luck. any idea's anyone.

monitor fuel pressures to see if they are dropping
