Hi Guys, can anyone out there help me.

Been running a H7 for a few months, no probs, good top end speed and low end acceleration with temps between 190-215f.

Last time out after a half hour of running, the buggy stalled after running flat out for 100 metres on flat tarmac. After letting go of the throttle, it slowed down under its own steam and suddenly died. Sounded similar to bogging when running rich just before she died. Checked temp- read 205f

She restarted straight away and off she went but has done the same a few times since. I've checked/replaced Glowplug, fuel line, pressure hose from pipe, all OK.

Otherwise the buggy runs like the wind.

Any clues Guys?
