Van is turning off after a while relays k1 and k2 are getting hot

Hi, K1 and K2 are "Run Accessory" and "Run" relays respectively. Have you tried replacing the relays? Beyond that, it sounds like a difficult electrical diagnosis that. needs to be performed, determining what needs to be done in the related circuits. Seems suspect to me that you'd have some kind of wiring problem, unless there is evidence of accident damage or other information we can't possibly know without discussion further.
