M2-106 with the Detroit MBE 906 Non EGR, Non DPF and related emissions systems. LPG Bob Tail truck, 5.000 gallon tank. Engine cranks no start. Scanned and was code for RPM signal. Ckt good, but low range signal. Replaced both crank & cam with OEM sensors. Same problem. It feels like it loses prime. When aided with starting spray, it starts and takes like 30 second turning low and thrilling. Later it stabilizes and idles normally. It can work the whole day normally. Good power. PTO. Everything. Next day, no start again. We are in the Caribbean. No Preheaters. No glow plugs. No ice. No snow. 30 Degrees. Only Sun, Sand, beaches and vacations. :-) I am leaning like there is a Prime loss. There is no fuel leaks anywhere. Fuel supply is good from tank. Perhaps I have an air intake somewhere on the fuel system? It seems it discharges overnight.

Please Help.

TIA.
