Oil light flashes (~1/2 second on, 1 second off, repeating) when it shuts down. Oil level right where it should be. Last couple times this has happened, it’s resolved itself after a couple restarts and waiting for it to warm up adequately. Today it’s not going so well 
Does not seem to matter whether I’m in bypass or spraying, soaping or rinsing. 
If it’s intermittent I’d wager the oil level sensor is either faulty or shorting out somewhere.
Last time this happened to me a few weeks ago it was the gas cap that wasn’t venting enough. Found the problem on a thread here. PWRA is great.
Alright. So my hunch might be right. Struggling to pull fuel. Bummer. I really liked using the truck’s fuel tank, but it might just be too long a run for the fuel pump to be happy about it.
If it will run on starter fluid, you’ve pinpointed a fuel issue.
Update?
Oil was right up to the top mark on the dipstick. I decided to let a couple ounces out the drainzit and see what happened. So far machine is running more smoothly; no more shutdowns yesterday or today.
But I really do think I need to install a dedicated fuel tank. I just don’t know where I’m gonna install it on this cramped rig.
Edit: the oil light on these machines seems to have different “codes” that it blinks. I remember when I had an electrical issue a couple years ago, it was a rapid flash. But for the life of me I can’t find a guide anywhere online on how to read the different codes.
