The hyster is a Mod# H100XM Ser# L005V04733C.
The machine operates for approx 30 min to an hour and the lite starts to flash after 2 min of operation. The engine shuts down completely like turning the key off and will not restart for 10 min or so ( it will not even crank over) but I still have all electrical power for options. It has only done this to me once which makes it very difficult to diag but the operator says it happens constantly.
Thanks for any info
